Process Capability for Non-Normal Distribution Using Minitab-Case study

The normal distribution also fits the data after they are transformed with a Box-cox transformation and Johnson transformation.
Use the Box-Cox transformation if your non-normal data are all positive and you want to obtain estimates of within-subgroup (potential) capability as well as overall capability.
Use the Johnson transformation if your non-normal data contain negative values or if the Box-Cox transformation is not effective.

Hi! Thanks for the video, great guidance!. . . Question: What do you do if your data has a lognormal distribution, but it fails the stability aspect? The data has points outside the control limits

Hi, thanks for the video. How does the concept (and the formulas) in cpk change in case we have a nominal target value?
