我们通过调整协变量并结合以前对相同遗传标记的潜在异质性研究的结果来研究标记的遗传效应的估计。在没有协变量的先验信息的情况下,该程序基于频率论和贝叶斯方法,同时最大化协变量系数的似然函数和最小化遗传效应的损失函数,因此被视为混合估计。虽然我们专注于病例对照遗传关联研究的应用,我们描述了一个一般的方法,为各种类型的性状。对于应用程序,我们表明,所提出的混合推理的基础上的前瞻性抽样可以适用于回顾性收集的病例对照数据。使用混合推理的模拟和应用。
We study estimations of the genetic effect of a marker by adjusting out covariates and incorporating the results of previous potentially heterogenous studies of the same genetic marker. Without prior information on the covariates, the procedures are based on both frequentist and Bayesian methods by simultaneously maximizing the likelihood function for the coefficients of the covariates and minimizing the loss function for the genetic effect, and hence are regarded as hybrid estimations. Although we focus on an application to case-control genetic association studies, we describe a general method for various types of traits. For the application, we show that the proposed hybrid inference based on the prospective sampling can be applied to retrospectively collected case-control data. Simulations and applications using hybrid inference are presented.
