Iptw cox model
Webway to obtain the estimates is by using a Cox model. To allow for non-proportional effects of FLC it was entered as a strata in the model, with age and sex as linear covariates. The assumption of a completely linear age effect is always questionable, but model checking showed that the fit was surprisingly good for this age range and population. Webstratification, inverse probability of treatment weighted (IPTW), stabilized IPTW, and matching. Strengths and limitations of each method are illustrated by estimating the …

WebApr 21, 2024 · I am using IPTW for Cox (survival model - proc phreg) model. However, it's said that the confident interval generated by this procedure will create bias even using a robust estimate. One stimulation suggested using bootstrap to obtain 95%CI. I have never done bootstrap before and I wonder how to integrate the inverse weight into the bootstrap.
