Abstract : For testing the equality of c continuous probability distributions on the basis of c independent random samples, various nonparametric tests for dispersions are offered. These tests, include among others, the multisample analogues of the twosample normalscores test of dispersion and the tests considered by Ansari and Bradley, Klotz, Mood, and Siegel and Tukey. Under suitable regularity conditions, it is shown that these tests have limiting noncentral chisquare distributions with c1 d.f. The asymptotic relative efficiencies (in the Pitman sense) of these tests relative to one another and the F test, are obtained and are shown to be the same as for the twosample problem. (Author)
