I then plotted the predicted residuals and saw they were nowhere near normally distributed. I know that REML is fairly robust to deviations from...

    Hello everyone, Might anyone know why, when running multilevel (mixed effects) models with REML I get completely different results when I run the same models with robust variances? I originally chose REML because I have a small number of clusters (11). However, when plotting the residuals for...
