Using y.bar to predict y: What’s that all about??

That solves the problem in that the coefficient for the group mean no longer exactly equals 1, and is no longer significant in randomly generated data. The thing is that the “outcome group mean” as predictor picks up on all differences between groups. The more groups differ, the stronger the effect of the “outcome group mean” will be.
