its probalby not as important to average these stats, but you can do
it the same way as you would with any other (scalar) quantity of
interest. so you just average them.

We are trying to model lme (mixed effect) with imputed
data from Amelia. We
calculated the averaged coefficients and standard errors obtained from five
datasets, but don't know how to average the model fits (AIC, BIC, or
-2loglikelihood) and random effect variances. I guess we can use the
standard error formula for the random effect variance (right?) but how about
the model fit estimates? Does anybody have a idea?
P.S: there is a typo in the section note about Amelia. Under the title
"combining estimates from the M datasets", Sq2 should be sum of (qj-qhat)^2
instead of (qj-qhat^2)
Thanks!
