Re: How to properly analyze the data fro popcorn example in JMP's sample files due to unequal varian

There is a in-depth description of the problem in an older version of the JMP DOE Guide

https://www.jmp.com/support/downloads/pdf/jmp_doe_guide.pdf . The popcorn example is used in the introduction chapter and documented including the analysis via GLM beginning with page 15. 

 

Hope that helps.

Tried it without success. Are you using the current V12 example for popcorn.jmp? The factors and response are different from that used in an earlier version that you recommended..
