From: A factor model to analyze heterogeneity in gene expression
Illustrative data sets: Individuals and genes representations. Individuals and genes representation using respectively the Z matrix corresponding to the factors and the B matrix of the loadings found by FAMT. Individuals and genes are colored according to the independent variable they are affected by. (A) representations corresponding to case 1, (B) case 2 and (C) case 3.
