SUMMARY. The minimum chi-squared test is obtained for testing the hypothesis that the smallest r eigenvalues of an m x m correlation matrix are equal, where r < m is specified in advance. One advantage of this test is that it provides as a natural byproduct a correlation matrix estimator that has multiplicity r for its smallest eigenvalue.
