Overall sensitivity and specificity of methods using three types of priors,under the full model, and BMA using the g-prior (gBMA), by ten-fold cross validation, on set (a): p = 340, n = 1260 and set (b): p = 1364, n = 1260. %pN F R: percentage of predicted nucleosome-free regions by each method; ave.corr: average percent correct classification = (Sens + Spec)/2, averaged over the ten cross-validation data sets. The average percentage of NFRs in the data sets was 43%. Note: It was not possible to use the gBMA procedure for set (b) due to the massive computational cost.
