Abstract:
1. A method for analyzing differences in an outcome between a subset A from a data set for a process and a subset B from the same data set, the method comprising a computer system automatically performing the following: processing a data set containing observations of the process, the observations expressed as values for a plurality of variables and for the outcome, wherein processing the data set determines behaviors for different variable combinations with respect to the outcome, the variable combinations defined by values for one or more of the variables, the subset A defined as those observations for which one or more test variables take first values and the subset B defined as those observations for which the test variables take different second values; for pairs of a first variable combination and a second variable combination, wherein the first and second variable combinations are the same except that the test variables take the first values in the first variable combination and take the second values in the second variable combination, estimating contributions of the pair to differences in the outcome between subsets A and B, based on differences in the behaviors of the pair and also based on differences in populations of the pair; and reporting differences in the outcome between the subsets A and B based on the estimated contributions for the variable combinations.
