Figure 2From: A hierarchical Naïve Bayes Model for handling sample heterogeneity in classification problems: an application to tissue microarraysPosterior probabilities of the three feature simulated experiment. Histograms of posterior probabilities of the three feature experiment (Exp.3, Table 2) on a simulated dataset. Panels A and B show the results obtained with the HierNB classifier for class 1 and 2 respectively; panels C and D show results obtained with the StNB classifier. In the upper right corner of each panel the frequency of the bin corresponding to the highest posterior probability range is reported.Back to article page
