The Misclassification Rate vs Number of Trees Plot plots the misclassification rate on the y-axis and the number of trees on the x-axis for the out-of-bag data. Each tree in the forest casts a vote for the classification for a row.

Interpretation

The misclassification rates must be ≥ 0. Lower values indicate a better classification model. If you use a test set in addition to the out-of-bag data method, Minitab displays a curve for each validation method.
