New eBook Release! Regression Analysis: An Intuitive Guide

By Jim Frost 94 Comments

I’m thrilled to announce the release of my first book! Regression Analysis: An Intuitive Guide for Using and Interpreting Linear Models.

If you like the clear writing style I use on this website, you’ll love this book! The end of the post displays the entire table of contents! Cover for my ebook, Regression Analysis: An Intuitive Guide for Using and Interpreting Linear Models.

Over the course of this full-length book (338 pages), you’ll progress from a beginner to a skilled practitioner. I’ll help you intuitively understand regression analysis by focusing on concepts and graphs rather than equations and formulas. I use everyday language so you can grasp regression at a deeper level.

You will learn practical tips for performing your analysis and interpreting the results. Feel confident that you’re analyzing your data properly and able to trust your results. Know that you can detect and correct problems that arise.

Regardless of your background, I will show you how to perform regression analysis. Students, career changers, and even current analysts looking to take your skills to the next level, this book has absolutely everything you need to know for regression analysis.

Buy it on Amazon (US site)!! Or go to my Web Store for other locations.

My Book Covers a Lot About Regression Analysis!

In this book, you’ll learn many facets of regression analysis including the following:

  • How regression works and when to use it.
  • Selecting the correct type of regression analysis.
  • Specifying the best model.
  • Understanding main effects, interaction effects, and modeling curvature.
  • Using continuous and categorical (nominal) variables.
  • Interpreting the results.
  • Assessing the fit of the model.
  • Generating predictions and evaluating their precision.
  • Checking the assumptions.
  • Examples of different types of regression analyses.
  • Downloadable datasets so you can try it yourself.
  • Answers common questions and concerns I’ve encountered over the years!

I’ve literally received thousands of requests from aspiring data scientists for guidance in performing regression analysis. This book is my answer – years of knowledge and thousands of hours of hard work distilled into a thorough, practical guide for performing regression analysis.

You’ll notice that there are not many equations in this book. After all, you should let your statistical software handle the calculations so you don’t get bogged down in the calculations and can instead focus on understanding your results. Instead, I focus on the concepts and practices that you’ll need to know to perform the analysis and interpret the results correctly. I’ll use more graphs than equations!

Don’t get me wrong. Equations are important. Equations are the framework that makes the magic, but the truly fascinating aspects are what it all means. I want you to learn the true essence of regression analysis. I want you to understand the essential concepts, practices, and knowledge for regression analysis so you can analyze your data confidently. That’s the goal of my book.

I hope you’ll enjoy it! Table of contents are below! Buy it on Amazon (US site)!! Or go to my Web Store for other locations.

    Dear Jim, thank you so much. Your response had been useful. I have also read some of your posts and they are very useful and interesting. You have the capability to present complex statistical concepts in simple non-statistical jargon. Thanks.

    Dear Jim, I hope you would also help me in answering one question: .

    I have four categorical variables: education (primary=0, secondary=1, tertiary =2 and higher=3), place of residence (urban=1, rural=2), wealth (poorest=1, poorer=2, middle=3, richer=4, richest=5), empowerment (low=1, medium=2, high=3). I want to create a new variable by multiplying these four variables: education*residence*wealth*empowerment, giving a variable with 120 categories. How do I label these categories automatically in Stata? Or how do I know that for example it represents no education and poorest and low empowerment and urban area? I want to know the name of combinations of each category of the variable so that I would be able to analyze my analysis by the categories.

    I would appreciate your help.

    Regards,

    Hello Dr, thank you.
    I have one question.
    In my cross tabulation, I have two categorical variables, one binary (yes, no), which is my dependent variable and the other has four categories. When I cross tab them, once cell ( that is, the “yes” of one variable and category #4of th other variable has a cell that has only 8 observations. Can I collapse/merge some of the categories of the four category variable into 3 or four for the cross tab? Could I use this variable ( that with small observations in one cell during crosstab) in multiple regressions without collapsing its categories?
    your help is much appreciated.

    • Jim Frost says

      July 20, 2022 at 12:53 am

      Hi, eight observations in that crosstab group is pretty low but it might satisfactory. Chi-square tests typically require a minimum group size of 5. While you’re not performing a chi-square test, it’s probably a similar require. Unfortunately, I don’t have a reference for that. You might be able to use the categories as they are.

      You can collapse the categories. It might help because the large number for that combination provides a more precise estimate of that combined condition, which gives more statistical power. Ideally, you’d define your procedures, including collapsing the categories, in advance to avoid the appearance of manipulating the results. However, you can give it a try to see the effect. In your writeup, you’d need to explain what you did and why.

    Regression analysis is used to predict values, but whats left to predict if “it’s not safe to extrapolate outside that range”?

      Hi Bengt,

      The problem is that the relationship can change outside the range of your data, and you’d be completely unaware of that fact–because you don’t have data for that region. So, yes, you can generate predictions outside of your sample space easily. All you need to do is enter the input values into the equation. But you really don’t know how trustworthy the results are. One common guideline is that it’s ok to go 10% outside of your sample space.

      Typically, you only want to make predictions within the ranges of your data because that’s the portion to which your model applies. You understand the relationships in that region because you have the data to model them with those values. Again, outside that range, the relationships can change!

    Hi Jim!
    On page 54 in your book you write: “Statistical software can’t take a categorical variable and directly analyze it. Instead, it converts categorical variables into indicator variables using a (0, 1) coding scheme.” Which software are you refering to? Excel and JASP does not seem to be able to do it for you.

      From my experience and reports by others, I know that Minitab, SPSS, Stata have this feature and I’m pretty sure JMP does.

      I would not consider Excel to be statistical software even though it has statistical functions. I’ve written about How to Perform Regression Analysis using Excel.

      I’m not familiar with JASP. I’ll take a look at it!

    Hi Jim.

    On page 43 in your book on regression analysi you write:

    “The height coefficient in the regression equation is 106.5. This coefficient
    represents the mean increase of weight in kilograms for every
    additional one meter in height. This study sampled preteen girls in the
    United States. Consequently, if a preteen girl’s height increases by 1
    meter, the average weight increases by 106.5 kilograms.
    The regression line on the graph visually displays the same information.
    If you move to the right along the x-axis by one meter, the
    line increases by 106.5 kilograms.”

    106 kg per meter. Thats’ a lot for a preeteen girl. I don’t not understand how the diagram says that.

      Hi Bengt,

      Be sure to read the next two paragraphs where I explain that in more detail. Specifically, I explain how the data range from 1.3 to 1.7m and, hence, it’s not safe to extrapolate outside that range. We can’t shift by a full meter. The technical explanation is as I describe, 106.5kg per meter. However, data limitations constrain that to less than a meter. That’s also an average. As you can see in the graph, some individuals are above and below the regression line.

      I hope that helps clarify it!

    Hi Jim,

    I am currently making my way through your new book and articles on here. These are very helpful and well explained. I do have a question that I am finding difficult to find the answer to within these resources.

    Currently I am doing a systematic review of the predictors of clinically significant weight gain amongst those who take antipsychotics. This is usually defined as a 7% or more increase in weight. My inclusion criteria will allow for both RCTs and non-randomised studies of interventions. My question relates to distribution of predictor variables. My understanding is that randomisation will allow for even distribution of potential confounders and baseline characteristics of participants. In an observational study, this may not be the case. My question relates to whether I should be prioritising RCTs over non-randomised studies of interventions because of this. As regression analysis will just be conducted amongst those who are treated with the drug, will baseline data, some of which might function as a predictor variable e.g. sex, be more evenly distributed if the sample arises through a randomisation procedure or not?

    I may be over-complicating this, as if I include for sex in the model – perhaps if accounts for this even if males vs. females are not evenly present within the sample?

    If the answer is within a blog post or chapter of a book of yours, please direct me. Any help you could give would be much appreciated – you can probably tell I am quite confused!

    Thank you,

    Ita

      Hi Ita,

      I write about this extensively in my Introduction to Statistics book. But, yes, when you are performing an experiment, randomized controlled trials (RCTs) are the best. However, they’re not always possible. Observational studies are an option and you can control for confounders by including them in the model. However, the case for a causal relationship is always weaker with observational studies. And there’s always a chance that there are confounders that you don’t include in the model. Maybe because you didn’t even measure them! But, yes, if you can’t perform an RCT, you’re thinking along the rights by identifying confounders and including them in the model.

      I’d recommend my Introduction book because I talk about the entire issue in depth along with the pros and cons of RCTs vs. observational studies. In my regression book, which it sounds like you have, I write about confounding variables and tips for handling those in chapter 7. But I spend more time comparing and contrasting RCTs and observational studies in my Introduction to Statistics book.

      I hope that helps!

    I’m sorry… you’re absolutely right about the transition from Adj SS to Adj MS! My problem was primarily regarding the ‘Experience’-row, as both my ‘Regression’ and ‘Major’-row were the same as yours, but given your answer it must be, that the ANOVA-function of my program is coded wrongly.

    I guess I have to figure out how my program is entering the values in its ANOVA-function or fiddle around with the function itself!

    Thank for your time and, again, some fantastic intuitively books!

    Hey Jim!

    Thanks for some awesome books!

    In your regression book, I’ve found something unexplainable. On page 68 in your statistical output table for an ANOVA test using your categoricalexample.csv data, I believe the ‘experience’ row is way off regarding the numbers. The ASS and MSS is the same, which doesn’t make any sense and when you sum the ‘Major’ and ‘Experience’ rows regarding ASS and MSS it doesn’t add up to the ‘Regression’-value as expected.

    In addition, I get something else when running the ANOVA myself regarding the ‘Major’-row.

    Can you confirm this is a mistake in the book, or is my statistical knowledge/output/program just playing games with me?

    Sincerely, Peter.

      Hi Peter,

      Thanks! I’m glad you’re enjoying the books!

      Those are all great questions because you have an eagle eye and you’re going beyond understanding only the most commonly used output. Yes, those values are all accurate!

      Regarding the Experience row. Keep in mind that the Adj MS value is simply the Adj SS/DF. For Experience, the degrees of freedom is 1. With 1 in the denominator, those two values will be equal!

      At first glance, you’d expect the Adj SS values to add up to the total. However, keep in mind that these are the adjusted values, which means that they are calculated for each variable after all the other variables are entered into the model. Technically, they’re not even from the same model. The variables are the same but the order they’re entered into the model is different. For this example, the adjusted values for Experience are calculated after Major is entered in the model. The values for Major are calculated after Experience is entered.

      That fact is often overlooked but it is a crucial aspect throughout regression. Remember that the interpretation for a coefficient is that it is the mean change in the DV given a one-unit change in the IV after accounting for the effects of all other variables in the model. That’s true when you use the Adj SS, which is the standard procedure.

      I can’t be sure why your program is giving you different answers for Major. However, if I had to guess, I’d say it’s because it’s using a different reference level. For my example, I use Statistics as the reference level for Major. If your application is using a different reference level, you’ll get a somewhat different answer.

      Thanks for writing!

    Thank you for sharing your knowledge through this blog. It’s really helpful!

    I’d like to ask if you know the Wald test for testing equality of regression coefficients to compare regression coefficients between groups. Is it discussed in your new book? I submitted in a peer-reviewed journal a research article where I used multiple regression modelling in understanding the technology integration in science and mathematics teaching. I have two separate models for science and mathematics teachers. The reviewer wanted to know if the regression coefficients of the independent variables differ between the science and math teachers.

    Thank you in advance.

    I have data of wildlife electrocutions on power lines (>300 events). The IVs of the individual electrocuted would be species, age, weight, rainfall on the day that the individual was electrocuted. I am looking to model that data to see which IV increases the model fit. But I am confused on how to input the DV as it appears to be yes to occurrence of the event, but there isn’t any other level such as no there wasn’t an event. So how do I code the DV? Thank you!

      Hi,

      Typically, you don’t want to extend the curve beyond the observed data. It’s possible that the relationship changes beyond your observed dataset. Consequently, I don’t believe there is a way to extend the curve beyond the dataset in Minitab. You could graph the function using other software. However, again, be wary of trusting predictions beyond the range of observed data! That’s a highly suspect practice.

      Hi Alice

      Thanks for buying my ebook.

      Yes, I cover that issue in my book. That’s known as datamining and takes advantage of chance correlations in the data. These chance correlations exist in your sample but don’t actually exist in the population. The concern for this problem increases when you trying fitting many models and then pick ones based mostly on statistical significance rather than letting theory guide you. Look in the book for the section about datamining. Also, in the section about how to specify the model, I write about the importance of letting theory guide you and not relying solely on significance.

      I hope this helps!

      Hi Todd,

      You definitely don’t need calculus. A tiny bit of algebra would be helpful for the context about equations for lines. A little knowledge about polynomials and transformations like the natural log might be helpful but not required. I explain them in the book.

      A bit of basic statistical knowledge would also be helpful. Such as a basic understanding of p-values, hypothesis tests, confidence intervals, and correlation. Again, it would be helpful to start with some of that knowledge, but I do explain how those concepts apply to regression.

      My book focuses on the practical usage of regression and understanding the concepts. It doesn’t focus on the equations behind how it works. There are a few equations where they help explain concepts. My goal is to get readers to be able to understand what regression analysis does, understand it conceptually, and then know how to use it correctly, identify and resolve problems, interpret the results, and defend the results.

      In short, I don’t assume extensive knowledge about math or statistics. But, a few basics for both would be helpful.

However, I do not cover penalized linear models as that is more of an advance method. I do include an example of binary logistic regression, but not in-depth. Perhaps I can cover those more advanced topics in the a followup book!

    Awesome! I can’t wait to read this book. I’ve been waiting for you to write a book for a long time now. You are, hands down, the best stats teacher I’ve ever come across. Where were you when I was struggling with this subject in university?!

    Dear Jim,

    I’ve bought your book, at least as a support of your work that you are doing here on this website. Your posts are very useful and provide me answers that I cannot find in any books about regression analysis.

    Best wishes,

    Jiri

    First, congratulations!
    Secondly, can users of other software find benefit from using your book to grasp the concepts and contents ?

      Hi Eric,

      Yes! The main goals of the book are to teach the concepts, best practices, model specification, interpretation, assumptions, problem solving, avoiding common traps, and so on for regression analysis. In short, I want readers to learn the skills for using regression. These goals all apply to regression analysis regardless of the statistical software someone uses. One thing I don’t do is detail the procedures for performing all of this in Minitab. That’s not the focus. The Minitab output I show should be relatable to users of other statistical software packages. Lots of graphs. And output tables that are similar to other applications such as ANOVA, coefficients, goodness-of-fit, etc.

      In my book, I use the same approach that I use throughout my blog posts. So, those should give you a good idea of what to expect.

      Hi Howard,

      I use Minitab throughout the book. I do like the idea of creating companion books for different software packages.
