MICE, by Stef van Buuren and others, is an R package with many similarities to our “mi“. Actually, MICE came first, and it’s recently been updated. Should be available as an R download very soon. It would be interesting to see how the programs differ. We should probably look more carefully into cases where they give different results.
Updated MICE package for multiple imputations
Shouldn't mi just be a front-end for MICE?
No. mi does things that MICE doesn't do (and I'm sure the reverse is true also). I think it's better for the two packages to be developed in parallel in the open-source world of R, then others can take from mi and MICE what they would like.
