Meta分析中回归斜率的合成
The Synthesis of Regression Slopes in Meta-Analysis
摘要：
Meta分析（相关研究结果的综合）方法的研究涉及了许多简单的研究指标，但很少关注回归斜率的总结问题。这部分是因为当真实的回归模型集合被累积时，会出现许多复杂的情况。我们概述了合成斜率所涉及的复杂性，描述了现有的分析方法，并提出了一个多元广义最小二乘回归斜率的合成方法。
英文摘要：
Research on methods of meta-analysis (the synthesis of related study results) has dealt with many simple study indices, but less attention has been paid to the issue of summarizing regression slopes. In part this is because of the many complications that arise when real sets of regression models are accumulated. We outline the complexities involved in synthesizing slopes, describe existing methods of analysis and present a multivariate generalized least squares approach to the synthesis of regression slopes.
