“…agreeing that PN is an interesting, intrinsic criterion for comparing estimators, several studies have been conducted using PN to evaluate a variety of different estimators. For example, Rao, Keating, and Mason (1986) develop a general theory to compute PN for univariate estimators, Dyer and Keating (1981) and Keating and Gupta (1984) use PN to compare particular types of scale estimators, Keating (1983) considers estimators of percentiles of location and scale using PN, and Lee and Peddada (1987) compare ratio estimators. Several papers have made comparisons of biased regression estimators using PN, e.g., Keating and Czitrom (1987), Keating and Mason (1988), Conerly and Hardin (1990), and Mason, Keating, Sen, and Blaylock (1990).…”
