Hello,

I have a dataset with a very large number of columns (>10000) and fewer rows, but still a lot (>4000). I want to impute some data with Amelia for use in Zelig. I know what variables I am interested in using in the regressions, but there are a number of missing values, so I was hoping I could leverage the rest of the dataset to come up with imputations for the variables of interest.

Hence, I only want to impute missing values in a few columns of my dataset, rather than spending loads of time imputing all the other values which I don't need and getting error 34 trying to do this. Problem is that I can't figure out how to exclude columns from being imputed without excluding them from the entire analysis.

I guessed this would be straight-forward, but I searched and searched and came up with nothing, so if anyone can help me sort this out, I would very much appreciate it.

            Thanks,

                   Drew
