Abstract

Proposes cusum‐cuscore procedures that consider equal weight past sample mean values and past sample score values. The objective is to compare the performance of the cusum‐cuscore and the ewma‐cuscore and in particular to investigate the number of past sample mean values needed to make a significant impact on the performance of the schemes. It will be shown by average run length calculations that the two schemes complement each other very well and that they perform significantly better than standard Shewhart, cuscore and cusum procedures.
