Model selection by BMA. This figure illustrates the membership of the 6 signature genes in the 21 models selected by the iterative BMA algorithm on the CML progression microarray data. The 6 signature genes are shown on the vertical axis, whereas the 21 models are shown in the horizontal axis. The widths of the columns are proportional to the posterior probabilities of the selected models. A red entry indicates that the corresponding gene is included in a given model.
