TECHNICAL DISCUSSION OF A METHOD OF CLASSIFICATION OF INDIVIDUALS CALLED ASSOCIATION ANALYSIS, AS IT IS SPECIFICALLY APPLIED TO PAROLE PREDICTION.

Abstract

ORDINARILY, IN ASSOCIATION ANALYSIS, USE HAS BEEN MADE OF THE STATISTIC CHI-SQUARE TO MEASURE THE ASSOCIATION AMONG ATTRIBUTES. THIS REPORT DISCUSSES THE USE OF TWO DIFFERENT STATISTICS FOR THE PURPOSE OF CLASSIFICATION ACCORDING TO A HIERARCHICAL SUBDIVISION PROCESS LIKE THAT PREVIOUSLY USED. ALTHOUGH THE PROCEDURE IS STRICTLY ONE OF CLASSIFICATION, NOT NECESSARILY FOR PURPOSES OF PREDICTION, THE ATTRIBUTES BY WHICH AN INDIVIDUAL IS CLASSIFIED ARE THOSE OFTEN FOUND ASSOCIATED WITH PAROLE OUTCOMES AND USED IN THE UNIFORM PAROLE REPORTS. TO EXPLORE THE USE OF THIS TECHNIQUE IN PAROLE PREDICTION, A POOLING PROCEDURE WAS APPLIED TO THE SUBGROUPS OBTAINED, RESULTING IN GROUPS OF PAROLED PRISONERS, EACH WITH SIGNIFICANTLY DIFFERENT PAROLE OUTCOMES.
