imputing values from another variable

[IsabelM]

Hi,

I was wondering if anyone knows whether it's possible in the case of missing values to impute the value of another variable?

Thanks again for any tips,

Yes, SPSS supports multiple methods of replacing missing values.

Depending on how you plan to approach your missing values, these can variously be found under (a) Transform -> Replace Missing Values, (b) Analyze -> Missing Value Analysis, or (c) Analyze -> Multiple Imputation -> Impute Missing Values.

However, imputing missing values correctly can be tricky and the process is often abused. Without knowing anything about your data it is impossible to make a recommendation but if you're unfamiliar with the theory then the following reference provides a pretty good overview of the current status of the research:
