From: Multiply robust estimator for the difference in survival functions using pseudo-observations
Simulation results with different sample sizes = 200 or 500 and different censoring rates = 25% or 50% in the scenario where proportional hazard assumption dose not hold based on 1000 replications. The red dotted line represents the true value, the true values of \(\Delta \left(t=10\right)\) or \(\Delta \left(t=20\right)\) are 0.2524 and 0.3816, respectively. IPW: inverse probability weighting; OR: outcome regression; MR, multiply robust; MR estimators are denoted as “MR-0000”, where each digit of the four numbers, from left to right, indicates if \({\pi }^{1}\left({\varvec{X}};{{\varvec{\beta}}}^{1}\right)\), \({\pi }^{2}\left({\varvec{X}};{{\varvec{\beta}}}^{2}\right)\), \({m}^{1}\left({\varvec{X}},Z;{{\varvec{\gamma}}}^{1}\right)\) or \({m}^{2}\left({\varvec{X}},Z;{{\varvec{\gamma}}}^{2}\right)\) is included in the estimator (“1” means yes and “0” means no)
