[R-sig-ME] Variance of the fixed effects lme4

[Simon Harmel]

Hello All,

The below website talks about the use of "the variance of the fixed
effects" in the computation of R-squared from a mixed model.

But what is "the variance of the fixed effects"? Is it the sum of
the diagonal elements obtained from:   vcov(fitted_model)?
