Table 2.

Classification results obtained with naïve Bayes, logistic regression, and random forest in a single-pass test as well as in 10-fold cross-validation over the entire combined data set.

Classifier	Test results (training on the first and test on the second data subset), %	10-fold cross-validation (the first and second subsets combined), %a
Naïve Bayes	64.1	66.6 (7.6)
Logistic regression	60.1	64.5 (9.0)
Random forest	67.4	69.5 (7.7)

^aThe values for cross-validation are the mean and standard deviation of the classification accuracy obtained over 10 test folds.
