public class CorrectMatrix
extends StatsMatrix

If your prediction is yes/no, or if you are only interested in stats on correctness and incorrectness, you can create a matrix which is 2xN, where N is the number of possible categories in reality, and data[0][i] indicates the number of wrong predictions of things belonging to catogory i (you predicted them as something other than i), while data[1][i] indicates the number of correct predictions of things belonging to category i.
