linear mixed model - problem/? with nested random effects
Sep 19, 2016 6:43 AM(1053 views)
I am using JMP 12 pro for a linear mixed model. I have two fixed effects and multiple nested random effects. When I set up the model as I think it should be I get 0 for the covariance parameter estimates for one nested effect. Why is this happening? I use a similar analysis in another linear mixed model and the same nested random effects doesnt give 0 so I assume I am not doing something right.
