[R-sig-ME] var(ranef(Random Effect)) not the same as the variance component

[D. Rizopoulos]

Yes, you do not expect these two be the same. The variance components are the prior variances of the random effects, whereas var(ranef(model)) is the variance of the posterior means/modes of the random effects.

Hello All,

A very basic question. Generally, `var(ranef(Random Effect))` may not
necessarily be the same as the variance component reported for that Random
Effect in the model output, correct?


Thank you all,
Simon
