Dependence of non-centrality parameter of variance homogeneity test on main effect of a factor. The top curve on each plot shows results for interaction effect βgF = 1, the middle curve is for βgF = 0.5, and the bottom curve is for βgF = 0.1. Each subplot shows different frequency of interacting allele. (A - 0.05, B - 0.4, C - 0.6, D - 0.95).
