Abstract
A total of 454 sampling experiments were performed on the groupings of 100 samples each from separate Poisson populations in order to establish estimates of frequency of rejection of the hypotheses of homogeneity by means of the z, or index of dispersion, test. Results of these artificial realizations are presented in Figs. 1–6, and compared with the corresponding non-central ξ2-distributions.It is a pleasure to mention the technical assistance of Dennis Hamilton of the Research Computer Laboratory in programming the detailed computational phases of this investigation, which was partially supported by the State of Washington Initiative 171 Funds for Research in Biology and Medicine.
