Methods for single marker association analysis are presented for binary and quantitative traits. For a binary trait, we focus on the analysis of retrospective case-control data using Pearson's chi-squared test, the trend test and a robust test. For a continuous trait, typical methods are based on a linear regression model or the analysis of variance. We illustrate how these tests can be applied using a publicly available R package "Rassoc" and some existing R functions. Guidelines for single-marker analysis are provided.
本文介绍了用于二元性状和定量性状的单标记关联分析方法。对于二元性状,我们着重于使用Pearson卡方检验、趋势检验和稳健检验对回顾性病例对照数据进行分析。对于连续性状,典型方法基于线性回归模型或方差分析。我们说明了如何使用公开可用的R包“Rassoc”和一些现有的R函数来应用这些检验。还提供了单标记分析的指南。
