Abstract: We consider the problem of testing the homogeneity of two components of a mixture with varying mixing probabilities and construct an adaptive test that minimizes the asymptotic probability of error of the second kind for local alternatives.
Keywords: Adaptive algorithms, local alternatives, models of mixtures with varying concentrations, test for homogeneity of two means
