Poisson variables

By Jim Frost

Poisson variables are a count of the presence of a characteristic, result, or activity over a constant amount of time, area, or other length of observation. Poisson data are evaluated in counts per a constant unit size.

With a Poisson variable, you can calculate and assess a rate of occurrence.
