On the adequacy of the -2 log [lambda] approximation in multivariate analysis

Exact distributions of statistics for the tests of hypotheses in multivariate analysis of variance and for the test of independence are compared z with the asymptotic -XL distribution for -2 log à s.

â Critica1" sample sizes have been recorded which indicate the magnitude of a sample needed so that the approximate technique may produce satisfactory results for testing at the .05 and .01 significance levels.
