I desperately need help with generating a matched control group through SAS. We have records of individuals which have been exposed. We have an unexposed control group. I need to match each exposed individual with control group individuals on 1:10 basis. The matching parameters are birth year and sex. Is there a way to do this so I do not have to match each birth year separately? Do you have SAS syntax or do you know a website I have to visit?
Hi Anni,
the attached PDF (written by Lori S. Parsons) gives you some SAS syntax and explanation for matching with PROC LOGISTICS. It computes a so called propensity score which allows you to balance the data quite efficiently.
Best wishes and good luck with it,
Horst
The paper Horst provided for you should work for your needs but if you still need help let me know and we can share code for a similar approach. Google searching should bring up a couple other matching algorithms.
Thank you Horst and Brian. We will try to use the syntax provided by Horst. :-)
There is also proc surveyselect, see ex http://www2.sas.com/proceedings/sugi29/209-29.pdf
