[R-sig-ME] Pooling results from lme4 models with weights

[Elliott, Lewis]

Hi all,

I have a series of multiply imputed datasets created with the MICE package. With these, I want to run mixed models which include weights using lme4, and pool the results across the multiply imputed datasets using Rubin's correction.

The MICE with() function pools fixed effects nicely, but does not appear to pool random effects. The mertools package has functions for pooling fixed and random effects but cannot handle models including weights. Does anyone know of a package or function which can pool fixed and random effects parts of lme4 models AND handle weights?

Many thanks,

Lewis Elliott
