| Summary: | An alternative test is proposed for some heteroscedastic normal populations with constant coefficient
of variations. To facilitate the application of the procedure, an efficient estimation algorithm is
shown for its means and the corresponding variance-covariance matrix. The next task is only to form the
test matrix. The chi-square test is then applied using the value obtained through simple matrix manipulations. |
