Run Charts

Perhaps I am missing something in the Run Chart platform? After producing a run chart, where is the analysis such as tests for clusters, trends, mixtures, oscillation, etc (with p-values).?

I just had a customer ask me this same question - overall in JMP we use Westguard and Western Electric rules and circle the points rather than use general p-values like Minitab. Test info is further down in this post.

Control charts can be done in the Control Chart Builder (Analyze -> Quality and Process -> Control Chart Builder). This is an interactive drag and drop control charting platform. There is a control panel on the left that will let us control different aspects of what we see, for example individual points versus the mean per x grouping variable.

The documentation goes through a few examples:

Here’s a description of the charts available:

and also here:

JMP uses Western Electric/Nelson rules (Test 1-8), testing beyond limits, and Westguard rules - the points that trigger these alerts are circled. Tests are described fairly well. So rather than getting just a p-vlaue like in Minitab, you will see the points circled with the test beside it.

Also, we can create custom tests, for example:

Here are a few resources to help you use JMP:

This is a general guide for moving to JMP from Minitab:
