Thanks, Linda –
Here are some references that you may find useful.
I haven’t gotten the Statistics in Medicine reference yet, but Don Rubin referred to it and two others in the “IMPUTE” thread “IMPUTE: Re: “Averaging” chi-square values (fwd)” as providing information about averaging Chi-squared values from SEM models on imputed data sets. There are some other notes in the IMPUTE threads re averaging R-squared values, but you already report R-squared for the imputation analysis. It would be nice to have the DF for the t-tests and the and an option for testing the Deviance, too!
