在这项研究中,我们研究了五种特征选择方法对混合模型(G-BLUP)和贝叶斯(Bayes C)预测方法性能的影响。我们使用全基因组SNP数据预测了2186名克罗地亚人和810名英国人的身高、高密度脂蛋白胆固醇(HDL)和体重指数(BMI)。使用所有SNP信息,Bayes C和G-BLUP在克罗地亚数据中的所有性状以及在预测英国数据时对高度和BMI的高多基因性状具有相似的预测性能。在英国数据中,Bayes C在预测HDL方面优于G-BLUP, HDL受中等大小基因座的影响。G-BLUP框架中SNP子集的监督特征选择为贝叶斯C提供了一种灵活、可推广且计算效率高的替代方案;但是,当使用监督特征选择时,需要仔细评估预测性能。
In this study, we investigated the effect of five feature selection approaches on the performance of a mixed model (G-BLUP) and a Bayesian (Bayes C) prediction method. We predicted height, high density lipoprotein cholesterol (HDL) and body mass index (BMI) within 2,186 Croatian and into 810 UK individuals using genome-wide SNP data. Using all SNP information Bayes C and G-BLUP had similar predictive performance across all traits within the Croatian data, and for the highly polygenic traits height and BMI when predicting into the UK data. Bayes C outperformed G-BLUP in the prediction of HDL, which is influenced by loci of moderate size, in the UK data. Supervised feature selection of a SNP subset in the G-BLUP framework provided a flexible, generalisable and computationally efficient alternative to Bayes C; but careful evaluation of predictive performance is required when supervised feature selection has been used.
