# 模型选择与模型平均在Meta分析中的应用研究The Application Research of Model Selection and Model Averaging in Meta-Analysis

Abstract: Model selection and model averaging have been the important issues which are researched by statistics and economic circles. This paper relies on theories and methods of Meta-analysis and takes the analysis of factors influencing legumes-rhizobium mutualism cooperative systems as an example. Then, the application results of model selection and model averaging method in meta- analysis are compared. The results show that model averaging method can be applied to meta- analysis and its performance is better than model selection.
