Qin, Guoyou et Zhou, Haibo, Partial linear inference for a 2-stage outcome-dependent sampling design with a continuous outcome, Biostatistics (Oxford. Print) , 12(3), 2011, pp. 506-520
The outcome-dependent sampling (ODS) design, which allows observation of exposure variable to depend on the outcome, has been shown to be cost efficient.In this article, we propose a new statistical inference method, an estimated penalized likelihood method, for a partial linear model in the setting of a 2-stage ODS with a continuous outcome.We develop the asymptotic properties and conduct simulation studies to demonstrate the performance of the proposed estimator.A real environmental study data set is used to illustrate the proposed method.
