Abstract:

The exact distribution of Mauchlys sphericity test criterion W absolute value of stn Sp sup p where S is the sum of product matrix from a sample of size N taken from a p-variate normal population, is obtained using contour integration and methods similar to those of U. S. Nair and Box. Tables of percentage points for p 2110, alpha .005, .01, .025, .05, .1 and .25 and various values of N including small are given and comparisons made with approximate percentage points using methods of 1 Box, 2 Mauchly, 3 Tukey and Wilks and 4 Davis.
