Multiple imputation - pooling results together

[keops9876]

Hi guys!

I have a problem. I'm doing multinominal regression. I have 195 cases but many values missing at some variables. I decided to do multiple imputation - 6 imputations. I also did Split - file and my variable imputation_ is a grouping variable.
But how do I get pooled results in my multinominal regression? With current settings I get results divided by imputation variable.
I use SPSS 20.

Tnx,

Uros

Looking at http://pic.dhe.ibm.com/infocenter/spssstat/v21r0m0/topic/com.ibm.spss.statistics.help/mi_data.htm, my best guess is: did you select Compare groups when splitting the file?
