hi
i have a data set with missing data on both continuous and categorical data
, for example smoking status (non smoker, ex smoker and smoker) i would
like to impute values for the missing data, my problem relates to the
categorical data, what techniques are available for imputing missing
categorical data and what programs would i need for the imputation, i have
access at the moment to spss and stata , if possible any references to the
use of missing data imputation would also be useful
regards
ann
