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.
