Hi, Id like to do some sample matching with propensity scores. Ive estimated the propensity scores:
glm1 <- glm(Exposed~Gender+ImagingCentreID+espad.3a+drinks.preg+espad.6+audit.total+ PDS.all, family=binomial, data=PBQ_110421) Now I would like to match on the propensity score and have an exact match on Gender and ImagingCentreID. How do I specify this in the command: M1 <-Match(Tr = Exposed, X = glm1$fitted) ? Sorry, if my question is trivial! But I am an absolute beginner in R.
