Joint monitoring of mean and variance using Max-EWMA control chart under lognormal process with application to engine oil data
Abstract The control charts are frequently employed in process monitoring to assess the average and variability of a process, assuming a normal distribution. However, it is worth noting that some process distributions tend to exhibit a positively skewed distribution, such as the lognormal distributi...
