Testing the homogeneity of variances in a two-way classification

G. K. SHUKLA

Department of Mathematics, Indian Institvie of Technology Kanpur, India

Approximations have been obtained to the null distribution of Bartlett's type of statistic for testing the homogeneity of one-way variances in a two-way classification. Simulation studies show that the approximations give satisfactory results even for a very small number of rows and columns.

Key Words: Bartlett's test statistic • Dirichlet distribution • Heterogeneity of correlated variances
