Hi, I'm using inverse probability treatment weighting for the propensity for vaccination, followed by Cox regression. My exposure is vaccination and my outcome is death in the first week of life. Can I add a random effect term for mothers who have had more than one birth (and subsequent death in the first week)?
thanks
Minda
