[R] Stratifying level-1 variance with lmer()

2008-02-05 Thread David Afshartous
All, I've fit some models via lme() and now I'm trying to fit similar models with lmer() for some simulations I'm running. The model below (fm1) has an intercept variance that depends on treatment group. How would one accomplish a similar stratification for the level-1 variance, i.e., the with
