Fig. 1From: A powerful nonparametric method for detecting differentially co-expressed genes: distance correlation screening and edge-count testFinite sample performance of the t approximation under low dimensions (d x =d y =1): (a) normal setting and (b) uniform setting. The histograms represent the sample distributions of the test statistic \(\mathcal {T}_{n}\) under independence null, and the curves are corresponding t curvesBack to article page
