Hazard Ratio Estimation using Cox Model Weighted by the
Estimated Propensity Score
Description
Estimates the log hazard ratio associated with a binary exposure using a Cox PH model weighted by the propensity score.
Propensity model is estimated using a simple logistic regression.
Variance estimation takes into account the propensity score estimation step with the method proposed by Hajage et al. (2018) .
Both the average treatment effect on the overall (ATE) or the treated (ATT) population can be estimated.
For the ATE estimation, both unstabilized and stabilized weights can be used.
