Hi all,
I'm studying a rare outcome and would like to do a 1:4 case-control match using propensity scores as there are numerous covariates that I'd like to control for. I'd like to use propensity scores to create a cohort of cases with matched controls before embarking on any further analysis (similar to the SAS 1:N case-control matching macro).
Below are the steps of my thought process and my questions regarding them:
1) Create ps score
- should i use a logistic vs. pscore vs. teffects vs. psmatch2? and how does one go about it?
2) Matching Process
- how do I match the cases to controls in a 1:N fashion? Ive seen the ccmatch command but it doesn't appear that it'll work well in this situation
I apologize for the rudimentary questions and thank you in advance for your help!
