Setting a specific column as subgroup ID in process screening platform

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.

Re: Setting a specific column as subgroup ID in process screening platform

Hi @ScatterJaguar23 ,

 

The Process Screening launch dialog gives you options to specify a Subgroup column. And also the option to specify a Subgroup Sample Size.

Take a look at the help documentation for this platform.

 

I hope that helps,

Phil
