However, the performance measures, such as Brier score, calibration slope, weighted accuracy, specificity, F-measure, G-mean, etc., are the other choices that may better estimate the model’s performance. 7.3. External validity The proposed model was compared with the limited number of ...
One column in the score matrix is redundant because the scores represent class probabilities in tree leaves and by definition add up to 1. Get [Yfit,Sfit] = oobPredict(b5v); Use rocmetrics to compute a performance curve. By default, rocmetrics computes true positive rates and false ...
