Cramér‐von Mises tests of fit for the Poisson distribution
John Joseph Spinelli, Michael A. Stephens · Canadian Journal of Statistics · 1997
Abstract Goodness‐of‐fit tests based on the Cramér‐von Mises statistics are given for the Poisson distribution. Power comparisons show that these statistics, particularlyA2, give good overall tests of fit. The statisticA2will be particularly useful for detecting distributions where the variance is close to the mean, but which are not Poisson.
