A NOTE ON CUMULATIVE SUM (CUSUM) CONTROL CHART FOR DOUBLY TRUNCATED GAMMA DISTRIBUTION.

The CUmulative SUM (CUSUM) control chart for a doubly truncated gamma distribution is developed by using the integral equation method given by Page (1954). The objective of this paper is to study the effect of truncation on average run length (ARL) of the CUSUM scheme for controlling the parameters when the variable characteristic is distributed as doubly truncated gamma distribution. An algorithm for estimating (ARL) is suggested and numerical results are provided. [ABSTRACT FROM AUTHOR]
