public class Tabulate
extends Keyed<Tabulate>

Simple Co-Occurrence based tabulation of X vs Y, where X and Y are two Vecs in a given dataset Uses histogram of given resolution in X and Y Handles numerical/categorical data and missing values Supports observation weights Fills up two double[][] arrays: _countData[xbin][ybin] contains the sum of observation weights (or 1) for co-occurrences in bins xbin/ybin _responseData[xbin][2] contains the mean value of Y and the sum of observation weights for a given bin for X
