[R] sample R code for multiple imputation

2005-06-28 Thread David Hwang
Hi,

I have a big dataset which has many missing values and want to implement 
Multiple imputation via Monte carlo markov chain by following J Schafer's 
Analysis of incomplete multivariate data. I don't know where to begin 
and is looking for a sample R code that implements multiple imputation 
with EM, MCMC, etc

Any help / suggestion will be greatly appreciated.

David

There is also the mice package at http://www.multiple-imputation.com/
which uses mcmc but is different to Schafer's packages.

Schafer's functions have been ported to R in the packages norm, cat, mix
and pan. Their documentation includes sample code illustrating how to
use them.

The aregImpute function in Hmisc provides a range of other imputation
models, if you're not set on using MCMC. The mitools package might also
be useful for dealing with the imputed values.

Hope this helps,
James
