Fig. 2From: GSAR: Bioconductor package for Gene Set analysis in RAn example of bivariate normal distribution illustrating specific alternative hypotheses for a hypothetical gene set of size p = 2. a The standard bivariate normal distribution; b differential distribution as compared to panel A; c differential mean (shift) as compared to panel A; d differential variance (scale) as compared to panel A; e differential correlation between two components as compared to panel A. While the left-side panel shows three-dimensional density plots, the right-side panel shows the corresponding contour plotsBack to article page
