[amelia] altering memory allocation in Amelia

I'm new to Amelia and I'm having problems with memory size. I have a STATA dataset with nine variables and 400,751 observations weighing in at 7.8Mb. I can load three of the variables - cost, age and sex - into Amelia (for windows) but the program crashes when I try to run it. There are only 29 missing records on the age variable and the other two are fully coded. The program crashes immediately when I try to load the full dataset. One of the variables - disability - has 58,162 missing records and this is what I really want Amelia to help with. I guess I've two related questions: Is my dataset so big that multiple imputation will take too long and I should revert to something like listwise deletion or least squares imputation, both of which STATA can handle easily? If it's not too big, how do I alter the memory space allocated by the program? - amelia mailing list served by Harvard-MIT Data Center List Address: amelia(a)latte.harvard.edu Subscribe/Unsubscribe: http://lists.hmdc.harvard.edu/?info=amelia
