Statistical option: MEASURES

[deleted_user]

Is it possible to perform a measurement of odds ratio (proc freq data;/ MEASURES)
on variables that are in two separate databases? For example in database pre-test have the two variables,:#correct and #incorrect, in database post-test I also have: #correct and #incorrect. Can I perform this option without merging the two databases or will I have to merge them to perform the odds ratio measure.

PROC FREQ operates against a single data set, so either the incoming data sets will need to be combined or in some cases summarized first and then combined.
