WinBUGS软件实现Meta分析的Doodle模型图的构建

Constructing the Doodle for Performing Meta-analysis in WinBUGS Software

WinBUGS软件实现Meta分析的关键在于构建贝叶斯统计模型,目前有手工编写代码和构建Doodle模型两种方法。手工编写代码具有灵活、方便的特点,但编写语言易错;Doodle模型的构建过程较为繁琐,但不易出错,且有利于加强对手工代码结构的理解。本文简要介绍使用WinBUGS软件行二分类和连续型数据的传统Meta分析、间接比较证据的Meta分析及网状Meta分析和有序变量的Meta分析时Doodle模型的构建。

The key for performing meta-analysis using WinBUGS software is to construct a model of Bayesian statistics. The hand-written code model and Doodle model are two major methods for constructing it. The approach of hand-written code is flexible and convenient, but the language programming is fallibility. The Doodle is complicated, but it is benefit to understand the structure of hand-written code model and prevent error. This article briefly describes how to construct the Doodle model for binary and continuous data of head to head meta-analysis, indirect comparison and network meta-analysis, and ordinal variables meta-analysis.
