On the small sample distribution and power of the log likelihood ratio and variance tests for the poisson

Abstract

The variance test and log likelihood ratio test are both well known in examining a series of n discrete observations for agreement with an assumed common Poisson distribution. This paper compares the tests in small samples with the corresponding x ² significance levels, and also the small sample power under several Poisson-type alternatives.
