Pnp*/Cnp* in Process Capability and Distribution platforms

[MShroff]

Hello,

I'd like to request that options to calculate Pnp* and Cnp* be added to the Process Capability and Distribution platforms. The following options for robust sigma could potentially be provided, or users could define their own settings and JMP could calculate the multiplier.

• 0.00135 – 0.99865: 1
• 0.005 – 0.995: 0.859
• 0.05 – 0.95: 0.548
• 0.1 – 0.9: 0.427
• 0.25 – 0.75: 0.225

The formula to use is shown below (for the first case listed above).

Thanks and regards

Mehul Shroff
