Some properties of misspecified additive hazards models

Lin and Ying [1994. Semiparametric analysis of the additive risk model. Biometrika 81, 61–71] proposed a simple inference procedure for the additive hazards model. In this article, it is shown that their estimator provides valid treatment comparison in randomized clinical trials even if misspecified and is consistent even if independent covariates are mismodeled.
