贝叶斯多项式回归模型在数量性状多遗传模型拟合中的应用

Bayesian Polynomial Regression Models to Fit Multiple Genetic Models for Quantitative Traits

Harold Bae, Thomas Perls, Martin Steinberg, Paola Sebastiani

摘要:

我们提出了一个连贯的贝叶斯框架选择最有可能的模型,从五个遗传模型(基因型,添加剂,显性,共显性和隐性)通常用于遗传关联研究。该方法使用遗传数据的多项式参数化同时拟合五个模型并节省计算。我们提供了一个封闭形式的表达的边缘似然正态分布的数据,并评估所提出的方法和现有的方法,通过模拟和真实的全基因组数据集的性能。

英文摘要:

We present a coherent Bayesian framework for selection of the most likely model from the five genetic models (genotypic, additive, dominant, co-dominant, and recessive) commonly used in genetic association studies. The approach uses a polynomial parameterization of genetic data to simultaneously fit the five models and save computations. We provide a closed-form expression of the marginal likelihood for normally distributed data, and evaluate the performance of the proposed method and existing method through simulated and real genome-wide data sets.
