A method of analysing untransformed data from the negative binomial and other contagious distributions
University of Wisconsin
We give a method of analysing data from the Negative Binomial and other generalized Poisson distributions which is free of certain disadvantages that arise when the data are transformed and then subjected to an ordinary analysis of variance. The method of analysis proposed is based on a statistic called
which is constructed from estimators given by Hinz & Gurland (1967 a). This technique can be used for testing a general linear hypothesis relating to untransformed data and it is illustrated here by means of an example based on a two-way layout.
