[amelia] Imputation too slow , and numerical options for tscs data?

Dear Prof King, I am new to Amelia. I try to impute a data set with 8400 obs and 32 vars in total, 14 vars have missing obs, some a lot like around 4 000. Since I have many missing obs, I set the ridge prior to 40, is that correct? I also chose time spline with k=1 and interaction with cross section, is that also correct option for a tscs data? My second question is: how long on average does it take to complete imputation? I am waiting for 12 hours and do not see any progress at all yet, the computer is running but there is no imputation yet. Is it because I put ridge option to 40 or because of many logical bounds and log transformations that I set for my vars? Thank you very much Suveyda Karakaya PhD Candidate The University of Tennessee
