The experiment was scripted through the free software Weka. The sample dataset (20 records) from Miami University Deception Detection (MU3D) database. Both (M5P and RepTree) methods tested related to training set and 10-fold cross-validation. These two methods are applicable to use with numeric classes. The analysis of M5P tree presented higher correlation related to REPTree, besides minor errors, and higher number of rules. Moreover, the elapsed time for processing is same in both methods. This specifies that the M5P and REPTree are models were suitable for predicting and extracting features.
