The impact on the predictive performance of the features and the coefficients of the two best models.

The second column shows the correlation coefficients of each feature with the class calculated on the training set (single regression coefficients - SRCs). The third column reports the F-measure values of the single attributes. Columns 4 and 5 display the estimated coefficients of the two best models: logistic regression on subset B and logistic regression on subset C; zero values correspond to removed features.
