Quantile residual analysis of the empirically-estimated null CDF of the Tpb statistic versus the null CDF associated with the \(\chi ^{2}_{4}\) distribution, theoretically suggested by Fisher’s method. a The kernel density approximations of the distributions of the \(\chi ^{2}_{4}\) (left) and the empirically-estimated (right) quantile residuals demonstrate closer agreement of the latter with standard normality than the former. b The Q-Q plot (green marks) of the \(\chi ^{2}_{4}\) (left) and the empirically-estimated (right) quantile residuals against the corresponding true quantile residuals corroborate the result in (a)
