摘要
metacor程序包是一款基于经典频率学理论研发的专用于在R框架下执行相关系数Meta分析的程序包。该程序包于2011年正式推出,可直接将相关系数作为效应量进行合并,采用的方法为DerSimonian-Laird法和Olkin-Pratt法。metacor程序包可以绘制森林图,操作简单易行,但仍有需要完善的地方。本文通过实例演示,介绍R软件metacor程序包实现相关系数Meta分析的方法。
The metacor, which is developed based on the classical frequentist theory, is a specified package for performing meta-analysis of correlation coefficients in R software. This package was officially launched in 2011. Based on the DerSimonianLaird method and Olkin-Pratt method, correlation coefficients can be directly pooled by using this package. The metacor package also can be used to draw the forest plot and is easy to use; however, it still needs to be improved. This paper briefly introduced how to perform a meta-analysis of correlation coefficients using the metacor package in R software through an example.
