Dear Dr. King, I am using Amelia for Windows. As I understand it, the usual sequence of steps is imputation - analysis - combination. Is it possible to combine the datasets before analysis? What I want to do is to replace the missing values, then combine all datasets into a single dataset (by averaging) and then perform the analyses. I need to do this because I want to create a factor score out of eight indicators and then use the score in further analyses. Is this an appropriate way of using Amelia? I would appreciate any ideas. Thank you, Claudiu Tufis
