Hello! I am conducting my first multiple imputation and I have a question regarding the creation of factor scores. I'm creating factor scores from variables that have missing data but other variables that I will be using also have missing data. I have been successful in creating factor scores using multiply imputed data in SAS. However, I also know that just because something runs doesn't mean it is correct. Is there a reason why I should not use factor scores generated from data that was imputed? I've been getting mixed messages. If I should not be creating factor scores after imputation, is it reasonable to create the factor score prior to imputation and then impute? I want to use the factor scores as predictors in a multinomial logistic regression model. Thank you in advance for any help!
