MetaAnalysisCorr: An SAS/IML Program to Synthesize Correlation Matrices with Hunter and Schmidt, Hedges and Olkin, and Generalized Least Squares Approaches

University of Hong Kong

Meta-analysis, the analysis of analyses, is a standard statistical procedure for summarizing research findings in behavioral sciences. The Hunter-Schmidt approach (Hunter & Schmidt, 1990) and the Hedges-Olkin (Hedges & Olkin, 1985) approach are the two most frequently used procedures. When dealing with multivariate cases, for instance, correlation matrices, these procedures are applied to individual correlation coefficients of the correlation matrix separately. A better approach, however, is to use the generalized least squares approach, which was proposed for multivariate effect sizes (e.g., Becker, 1992, 1995; Hedges & Olkin, 1985).
