THE PRESENT ANALYSIS IS BASED ON THE RESULTS OF PRIOR STUDIES CONDUCTED BY THE PAROLE DECISION MAKING PROJECT OF THE NATIONAL COUNCIL ON CRIME AND DELINQUENCY. THESE STUDIES, BASED ON DATA OF APPROXIMATELY 2500 PRISONERS IN THE FEDERAL CORRECTIONS SYSTEM, DISCOVERED NINE BIOGRAPHICAL AND INSTITUTIONAL VARIABLES WHICH COULD BE USED TO PREDICT PAROLE OUTCOME. THESE NINE VARIABLES ARE PRESENTLY EMPLOYED BY THE U.S. PAROLE BOARD IN PAROLE DECISIONS. THE MAJOR THRUST OF THIS REPORT WAS TO TRY ANOTHER MULTIVARIATE ANALYSIS ON THE SAME DATA UTILIZED IN THE EARLIER STUDY. THE ANALYSIS CONDUCTED FOR THIS REPORT INDICATED ONLY FOUR OF THE NINE VARIABLES ARE REQUIRED. IT ALSO DEMONSTRATED THAT REPRESENTING THE FOUR VARIABLES BY A SUM OF SCORES CAN HIDE DISCRIMINATION POWER AVAILABLE WHEN EACH PRISONER PROFILE IS VIEWED AS A FOUR-DIMENSIONAL ARRAY OF DATA. A TECHNICAL APPENDIX APPEARS AT THE END OF THE PAPER AND DESCRIBES THE METHODOLOGY OF CONTINGENCY TABLE ANALYSIS WITHIN THE CONTEXT OF PRISONER PROFILE DATA AND PAROLE OUTCOME.
