I am getting an error message after executing ICE in STATA 9. I am
using the following syntax.
. ice mdrgnc-mdrsvc mdsm_quit-mdr50 mdrk10000-mdrk24200000
> mcrk390000-mcrk24180000 crgnc-csm_quit crk10000-crk1060000 crk180000-crk24200000

> trace("C:\Users\Woolton Lee\Documents\Research\Summer 09\Thesis Papers for Publication\HMO cost function paper\qualtest");
The error I am getting is the following,
Imputing postfile: variable mdrk120000_mean already exists
r(110);
What is confusing is that I don't have a variable mdrk120000_mean in
the dataset I am running the imputation on. I realize this is part of
the algorithmn that ICE uses but I am not sure what I can do about it.
Thanks for your help,
Woolton
