Limited Translation Shrinkage Estimation of Loss Rates in Marine Corps Manpower Models.

Abstract

The use of shrinkage type estimators for the attrition rates in manpower flow models is extended to include the limited translation James-Stein technique introduced by Efron and Morris. The performance of these estimators is compared with that of several natural estimators on two scales: the original scale of rates, and the Freeman-Tukey transformation scale which was chosen in order to give shrinkage estimators more efficacy. Generally, the aggregate methods currently in use are outperformed by MLE, transformed scale cell average, James-Stein, and limited translation James-Stein. The results among the four were mixed when both global and small inventory cell figures of merit were compared. It is felt that better data aggregation will permit limited translation to excel in low inventory estimation. Keywords: Shrinkage estimators; James-Stein estimators; Manpower flow models; Low inventory estimation.
