Hi,
Thank you for your mail. I have used the link that you provided and got ice to work. The problem that I now have is that  I am using  a user written program called levpet that generates values of a variable  (Total Factor Productivity) for a firm using a non-linear algorithm. This variable is created using data on employment, net value added and capital. I have  large number of missing values on employment.  If I generate values of the missing observations for employment  in my original data set using ice, I get n number of imputed data files (where n is the no. of imputations). When I load them into memory, I cannot get levpet to work over all data sets (at least I do not how to get levpet to generate imputed values of tfp over several data sets) to generate the TFP measure. Therefore, I am using values of employment imputed from salary and wage data.  Given the limitation that I face, what steps can I take to ensure that impute does a reasonable job.
 Would reporting the correlations between salaries and employment for non-missing observations help? Is there any method for setting a bound on the prediction error that is unaccounted in the impute command?
