Pooled results not produced for standardized regression coefficients with multiple imputation

Troubleshooting


Problem

I'm running a linear regression in SPSS Statistics using data with multiple imputations to handle missing data. I want to see standardized regression coefficients among my pooled results, but these are not given. Can I get these?

Resolving The Problem

These are not currently produced. An enhancement request has been submitted to SPSS Development. For the time being, you can get these by standardizing each imputation's data using the DESCRIPTIVES procedure with SPLIT FILE and running the regression using the standardized variables. The unstandardized regression coefficients would then be the standardized coefficients for the original imputed data.

For example, if you are regressing y on x1-x3, using imputed data, some minimal command syntax might be (if the data are already sorted and split by Imputation_, the first two lines can be skipped):

SORT CASES BY Imputation_.


SPLIT FILE BY Imputation_ .
DESCRIPTIVES y x1 x2 x3
/SAVE.
REGRESSION
/DEPENDENT Zy
/METHOD=ENTER Zx1 Zx2 Zx3.

Then the standardized and unstandardized regression coefficients for each imputation are the same, and the pooled unstandarized coefficients give the values that would be obtained by pooling the standardized coefficients.
