How to calculate Cpk with specified sigma

Created: Sep 16, 2022 02:44 AM  |  Last Modified: Jun 8, 2023 08:54 PM (662 views)

Hi All,

I used to be able to calculate Cpk with Robust Standard diviation, typed in in the "Specified Sigma" box. But I couldn't find it in JMP16 any more. Please help. Thank you.

Under process capability options you can enter a user-specified value for sigma:
