Probability density distribution and scoring matrix for the yeast data. The joint probability density distribution h(x; y) of the yeast data set (panel A) and the respective distribution of log-scores s (panel B). x- and y-axes are log-ratios. The intensities of the bivariate functions are given in colors. Hot colors represent higher values as scaled in the colorbars on the right. In this study, N = 4461 and ρ = 12. Genes were considered modulated if x _k > |0.5| in at least one experimental condition.
