Pooled Regression Results not showing in output?

  • 1.  Pooled Regression Results not showing in output?

    Posted Fri July 24, 2020 04:17 PM

    I have a dataset with n=343 original data. Within this dataset, I have 50 imputations. I am trying to run a regression to see pooled results. In my output, I am seeing results based on original data and results based on each of my 50 imputations but NOT pooled results. I already checked and made sure that Pooled Results was checked off in the Edit > Options menu.

    Any thoughts? Thanks in advance!

    I gather that you are using the MULTIPLE IMPUTATION procedure. The pooled results should appear at the end, although in some cases there are statistics that don't have a pooled result.

    However, 50 is way more imputations than are generally used. Try using just 5 to see if the pooled results appear in that case.

    Sometimes pooled results cannot be produced because the model varies across imputations. For example, if you used stepwise, the selected model probably varies somewhat, so pooled results are not available.
