Abstract
This paper investigates the asymptotic properties of a modified likelihood ratio statistic for testing homogeneity in bivariate normal mixture models of two samples. The asymptotic null distribution of the modified likelihood ratio statistic is found to be χ 22 , where χ 22 is a chi-squared distribution with 2 degrees of freedom.
