Abstract:
|
Classically, it has been common in industry to employ CUSUM charts for monitoring non-conforming fractions which follow binomial distribution. Here we extend this methodology to accommodate binomial distributions in which the number of trials are variable. We employ Binomial-Poisson compound distribution and develop CUSUM chart threshold tables for desired ARL under both in-control and out-of-control processes. We apply the method to data on C-section deliveries.
