Webbbias, we adapt Robins’ rank preserving structural accelerated failure time model and g-estimation method. We show in simulation studies that this approach corrects the bias contained in previous studies. We estimate that the effect of winning an Oscar Award on survival is 4.2 years, with a 95% confidence interval of [−0.4,8.4] years.
