users.stat.umn.eduRandom effects are random variables in the population Typically assume that random effects are zero-mean Gaussian Typically want to estimate the variance parameter(s) Models with fixed and random effects are calledmixed-effects models.

www.stata.comeffects. For a linear model without random effects with independent and identically distributed (i.i.d.) errors, the distributions of the test statistics for fixed effects are tdistributions with the residual DF. For other mixed-effects models, this method typically leads to poor approximations

cran.r-project.org1.1. Linear mixed models Just as a linear model is described by the distribution of a vector-valued random response variable, Y, whose observed value is y obs, a linear mixed model is described by the distribution of two vector-valued random variables: Y, the response, and B, the vector of random effects.
