Martin, you might want to read some of the following good articles that explain how pooled estimates are computed (using a method due to Rubin). The "fine manual" might also be instructive.

Dear list: First time user of SPSS's multiple imputation procedure. After running this procedure the output generate provides data sets for each imputation. Thus, if I requested 10 imputations I obtained 10 different data sets with imputation values for those that were missing data points. Although It seems like one could simply get the average of all of the imputed values for those folks with missing values SPSS does not create a new data set with the average values or any measures of error associated with the imputed values. I would be curious to know what other folks have done using spss after they have run the multiple imputation procedure. martin
