Abstract:
1. A computer-implemented method comprising: providing, by a computer, a first data matrix and a second data matrix, each of the first and second data matrices including one or more variables, and a plurality of data points; determining, by the computer, a first score from the first data matrix using a partial least squares (PLS) analysis or orthogonal PLS (OPLS) analysis; and partitioning, by the computer, the first and second data matrices row-wise into a first group and a second group based on the first score of the first data matrix, and a penalty function that evaluates the first group and the second group based on (a) the variance of the first data matrix, and (b) a variance in the first and second groups relative to the variances of the first and second data matrices.
