Abstract

Three tests (likelihood ratio test, Wald test and Score test) are derived for the hypothesis that the coefficients of variation of k Inverse Gaussian populations are equal. The k samples may be of unequal size. The usual x²-approximation is used to investigate the behavior of the three tests under the null hypothesis and to compare the powers of these tests via a simulation study. Independent samples of equal and unequal size from the Inverse Gaussian distribution were used.
