when do you use reml for mixed models do mixed models use reml reml definition for mixed models reaml variance calculation can I use reml and reml in mixed models why use reml and ml when to use reml mixed model can you use reml for a fixed variance model when to use reml in mixed model what to use reml does reml ignore the fixed why use reml is reml biased what is the difference between reml and remerl what is reml variance why do we use reml when fitting models when reml should the fixed effect be compared to the reml model? how to figure out if model is linear mixed what is reml used for what's the difference between reml and ml
