Non-normal distributions in the Process Capability and Process Screening PlatformsHi all,
I am writing a script to aid my team in analyzing process capabilities for many properties across a variety of products. It seems like the Process Capability and Process Screening platforms are the ideal way to do that, but I'm struggling to get those platforms to handle non-normal distributions. When I assign Distribution or Process Capability Distribution properties to a column, the platforms either ignore them or try to use a bizzare (Johnson?) distribution. I'm using JMP 16 but could upgrade to 17 if it makes a difference.
- What distributions do the Process Capability and Process Screening platforms handle? The documentation mentions that they don't handle as many types as the Distribution platform but doesn't say which ones they do handle. I'm a simple person, I just use normal, log-normal, and Weibull.
- Should I assign distribution types to the "Distribution" property or the "Process Capability Distribution" property? And why are there two properties for the same thing?
- Will the Process Screening platform use either the distribution or process capability distribution?
Thanks!
