Percent agreement for rater calculation in attribute gauge study

Hello.

Can anybody explain what is meant by "number of uncounted matching levels for this rater k within part i for rep j" in the "Statistical Details for the Gauge Attribute Chart" section of the JMP Documentation Library (page 4760 out of 7278)? Also how the example calculation using the data in Table 7.1 is done? Screenshots of the relevant JMP Documentation Library pages are attached.

Thank you very much.

This is how I understand "number of uncounted matching levels for this rater k within part i for rep j" based on the example calculations ( Quality and Process Methods > Attribute Gauge Charts > Statistical Details for Attribute Gauge Charts > Statistical Details for the Gauge Attribute Chart ) but I could be totally wrong and just got lucky.

F or A and B rater

How many ones there are

 

Still how many ones are, but now we have already counted one 1 in step 1

 

How many zeros there are

 

And similarly for C:

Hi. Thank you. This is very helpful, although I do not understand the logic of the process. If JMP could provide a reference, that would be useful.

Regards.

The JMP help is not meant to teach statistical methods (or the reasoning behind the different methodologies).  That being said, if you want to understand the methodology search Inter-class correlation and Kappa.

 

This is the JMP help section:
