Abstract��

Considering the model of stochastic effect variauce analysis in two times repeated trials,
we present in this paper a method to test the homogeneity of the error variances, i.e.,
to test $H_0:\sigma_1^2=\sigma_2^2$, by use of the piecewise likelihood ratio test, and
then give some concrete conclusions according to three common
models.
