Dear Members fo News Group, I always appreciate that I could have received your help. As I know, I can apply Kolmogorov-Smirnov goodness-of-fit test to univariate sample. But, I don't know which method can be applied to multivariate samples, especially, when I got the samples assumed to be bivariate normal distributions. Please answer me ..... Thanks in advances.
