Hello I am a new user of Amelia II, and multiple imputation in general. In trying to run an imputation on a rather large dataset, I have come across the error below. Looking through the list's archives, I see it is advisable to work with pared-back datasets containing subsets of variables, to see where the problem is. I will try that, however I wondered if this error might have arisen from another issue? I would be grateful for any assistance anyone could offer.
