Well, it does not mean the model is wrong Jason, we are just talking about
different ways of summarizing the same data.
I was actually wrong in guessing it set the random intercepts to 0, it
appears to just calculate them through. See an excel spreadsheet I did
quickly when printing off the random intercepts in this example,
https://www.dropbox.com/s/cu3mbgpof1klech/EMMEANS_Example.xlsx?dl=0You could calculate the EMMEANS yourself, I show how to set the random
intercepts to 0 overall (which gives you your expected behavior Jason of
marginal = estimated). I don't know offhand how folks do the standard error
estimates for EMMEANS though.
If folks from SPSS pay attention here, this suggests it would be useful to
add an option to /EMMEANS_OPTIONS to set the random effects to particular
values, e.g.
/EMMEANS_OPTIONS SUBJECT=0
or something like that. Currently only supports setting the fixed effects to
particular values.
