Nettet30. mar. 2016 · Mixed models work by providing some shrinkage to the random effects, this is the b s in the Y B = b ∼ N ( X β + Z b, σ 2 I) model. Compared to their values as β s as fixed effects, the b s are shrunk towards zero, which would be the same as not including the effects in the model as either a fixed or random variable.
NettetLME models assume that not only the within-cluster residuals are normally distributed, but that each level of the random effects are as well. Vary the level from 0, 1, to 2 so that you can check the rat, task, and within-subject residuals.
