How to calculate Cpk with specified sigma

[#1]

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:
