I need to replicate mixed effect model made in SAS using Proc HPMIXED in R. I am using lmer of “lme4” package. Need help with the syntax, as I have 4 levels/hierarchies to account for the random effects I don’t know how to write the code in that case and how to interpret with the model it would build. Any help is appreciated. Thanks in advance
