The specific objective of the research reported here was to develop a computer-based statistical system which is general in nature but could yield some tentative answers to questions concerning interactions between groups of individuals and their attributes when predicting some criterion of success. The particular advantage of the technique developed here is that it is multivariate in nature, that is, complex multiple interactions may be handled simultaneously. If differing profiles on multiple background characteristics do indeed lead to unique prediction systems, the computer will isolate these groups along with their unique descriptive character.
