In the process capability analysis launched within a distribution plot, you can select a column as the subgroup ID (to generate Ppk and Cpk appropriately)
The process screening platform does not have this option. I believe it uses the standard subgroup sample size of N=2. This results in the Cpk and Ppk results not really being meaningful for my usage. I would like to know if there is a way to select a column as the subgroup in the process screening platform.
