Example of MSE decomposition. Example figure showing the relative contributions of the three sources of variation to the mean squared error. This is a scenario from one entry in Table 1. Plots for all other scenarios associated with Table 1 and [Additional file 1: Supplemental Table S1]. Here there is m = 1 informative gene, n = 200 total samples available for study, and the standardized fold change for the informative gene is 2δ/σ = 1.0.
