Using Help>Index look for Fit Distribution. You will find info on trying
various continuous distributions. Using Help>Index look for Capability
Analysis to find info on calculating Cpk for non-normal distributions.

data for Control Limit/Cpk analysis?
any more detailed comments how to do that in JMP?
