Hello,

I was running regressions with the imputed variables, and I got R and R2 over .90. Is this ever possible? The highest R2 I had with original dataset was over .50.

I used SPSS Multiple Imputation and Missing Value Analysis functions by following all steps suggested by the IBM SPSS guide. The original dataset had a significant amount of missing values (about 10-40%). Some variables imputed are at the scale level as well as the individual scale items. I spoke to my advisor and she, too, is skeptical about this result.

Any suggestions would be appreciated. Thanks much.
