Hafdahl, A. R. (2017, July). Heteroscedastic effect-size estimators
in random-effect meta-analysis. Paper presented at the meeting of the
Society for Research Synthesis Methodology, Montreal, Quebec.
Research Areas: Numerous topics in meta-analysis, with particular attention to correlations, multivariate or clustered effect sizes, missing or "degraded" data, distributions of effect-size parameters, and functions of heterogeneous effect sizes (e.g., meta-analytic path models from correlation matrices).
