Hi -
I have noticed that in Control Chart Builder, JMP 18.2.1, if I create a P chart, JMP provides options for warnings for a number of different Nelson & Westgard rules. However, if I switch to Laney P', only "Test Beyond Limits" is an option. I'm curious if someone can explain the reasons why ... software bug? Good statistical reason those tests aren't applicable for a Laney P' chart? Something else entirely?
Thanks in advance.
