Birgit,

not knowing your data, I would recommend R-package "mice" or function
aregImpute from R-package Hmisc as good multi-purpose tools.

Regards, Ulrike

RSiteSearch("imputation", restrict="functions")

RSiteSearch("{multiple imputation}", restrict="functions")

  return many relevant hits.

[R] missing data imputation - simulation

2008-06-04 Thread Birgitle

My dataset contains missing data and I would like to do something like an EM
algorithm or a Markov Chain Monte Carlo approach to get rid of the missing
data.

Is there a function for imputation or simulation of missing data apart from
those in the randomForest library?

Thanks in advance

Birgit
