- Title
MEAN AND RANGE CHARTS FOR SKEWED DISTRIBUTIONS – A COMPARISON BASED ON HALF LOGISTIC DISTRIBUTION.
- Authors
Srinivasa Rao, B.; Kantam, R. R. L.
- Abstract
The well known variable control charts for average and range of subgroups for skewed distributions are constructed by two different approaches. One from the first principles of using the percentiles of sampling distributions of sample mean and sample range. Another approach is a skewness correction procedure depending on the coefficient of skewness. The coverage probabilities in both the approaches are computed through simulation and compared.
