> The Logistic Regression algorithm requires that category labels be labeled as 0 up to the number of classes-1. It should be able to handle any set of category labels provided by the user. B_out should have the appropriate size regardless of the values of the labels given, and the algorithm should also preserve the original labeling for the user.
