Percentage Points of Many-Outlier Detection Procedures

Abstract

In this paper the percentage points for the ESD, KUR, and RST many-outlier procedures that were introduced in Rosner (1975) are presented. A brief description of these procedures and some of the issues involved with evaluating their power are presented in Section 1. The algorithm used to estimate their percentage points is given in Section 2, and percentage points for N = 20(10)60(20)100 for k = 2(1)5 are presented. An example to illustrate the use of these percentage points is given in Section 3. Related investigations conducted by the author are reported in Section 4.
