st: impute items and total sum scores of a scale

[Paula Arce <paulaarce@rocketmail.com>]

Hi All, 


I am using mi ice to impute missing data into my data set. I need to impute both single items and total scores of my scales. 


I will be using the data for SEM analyses which is why I need to impute the individual items but I am also imputing interaction terms to account for moderation effects - to create the interaction terms I am multiplying  total scores of the scales which I enter in the passive statement. 

When I run the command, I receive the following error message:


Error #301 encountered while running -uvis-
I detected a problem with running uvis with command ologit on response AUDIT
and covariates 


you may wish to try the -persist- option to persist beyond this error.
dumping current data to ./_ice_dump.dta
last estimates not found

I am not sure how to address this - can anyone help?

Thanks!
