[amelia] Fwd: amelia problem

Hello, I have been trying to use the most recent Windows version of Amelia II for multiple imputation of my dataset (and I have the most recent windows version of R installed: 2.3.1). My data have a max of 5 time points for about 8500 respondents (ends up with 33559 observation rows). In the options, I identified the timepoint variable (ranges from 1 to 5) as the time series index and the person id # as the cross sectional index. Then I identified which variables were nominal (which adds about 20 dummies altogether). I left the TSCS options at the default. And for priors I set boundaries of 0 to 1 on the dichotomous variables (about 5 of those), and set the boundary of 0 to 6 for one variable that I know should not extend beyond this range. I am loading the data from Stata and requesting that the 5 output datasets also be in Stata format. I keep getting an error message similar to the following: <<<<< There was an unexpected error in the execution of Amelia. Double check all inputs for errors and take note of the error message:Error: cannot allocate vector of size 219444 Kb I started by including all possible interactions, which involved a dataset of 92 variables. But even after I took out the interaction variables and tried to run it with only 18 variables (although it is more like 38 if you account for the dummies created for nominal variables), and it still gave me the above error message. This was also after increasing the workspace to 256MB (when the computer has 512MB of RAM). Is the dataset just too large for the program? Or am I doing something else wrong? Thank you for whatever help you can give me. Sincerely, Kristin Burnett
