Disclosed is an algorithm for finding the optimal split in the sample space of a continuous random variable. If (X,Y) has a distribution such that Y has two possible values and X is continuous (e.g., a multivariate Gaussian mixture), then for predicting Y the best question about X cannot be found either by exhaustive search or by sorting the conditional probabilities P(Y = 1 X = x) as in the case of X with finitely many values. An algorithm is given to define the optimal split (question) in the continuous case.
