I am trying to analyze one of my experiments that was created in and I am having some trouble understanding the parameter estimates.
Depending on which interactions I choose to analyze ( i chose only up to 2 way interactions since this is a fractional factorial design) the parameter estimates either say unstable, zerod and in some other cases empty. I am hoping to et some clarification on why this comes up and what it means.
I have a included a screenshot below.
I am currently using JMP 17 on Windows
