Time-dependentmodel(extendedCox): However,employmentstatus changes over time, and it may be the more recent employment status that would affect the hazard for re-arrest. For example, if a person lost their job they might revert to crime. In order to account for time, we might want to ...
Dear Stata list, I am trying to reproduce the weighted time dependent Cox model (Andersen–Gill format with IPTW) results in Stata that are originally obtained from R using same dataset, but so far getting the estimates different. Could anyone indicate what I could be done to fix this? Any...

摘要: One of the strengths of the Cox model is its ability to encompass covariates that change over time, due to the theoretical foundation in martigales. A martingale (original definition) is a betting strategy in games of chance. One of the simplest and best known is doubling the bet...
