Abstract

The well known variable control charts for mean and range of subgroups for a skewed distributions , Exponetial-Gamma are constructed by two different approaches. One from the first principles of using the percentiles of sampling distribution of sample mean and sample range and the other is based on the popular Shewart control limits. The coverage probabilities in both the approaches are computed through simulation and compared.
