Multiple Imputation
Locked
 
|
Dear SPSSX, I have performed the multiple imputation technique for filling out my missing values. Now, I have my original data set, PLUS 5 sets of imputed values. How do I produce a data file with only the 'Pooled Variables' to be used for further analysis? There must be some kind of command in SPSS that can be done to resolve this issue? Thank you in advance Med venlig hilsen / Kind regards Halil Tokay |

Dear Halil, Multiple imputation does not pool results at the data level, only at the analysis level. That is, it estimates the missing values multiple times,
the same analysis is then carried out for each imputed data set, and results are then pooled into one final analysis. The imputed values themselves are not pooled. Best regards, Joost van Ginkel From: SPSSX(r) Discussion [mailto:[hidden email]]

When I take a MI data set and split it by MI variable (original, MI_1, MI_2, MI_3, MI_4, MI_5) and then run my analysis (say t-test, or MRA) I get the results
for each level of the split file along with the results for the pooled data. mfs From: SPSSX(r) Discussion [mailto:[hidden email]]
