Weighting by Inverse Variance or by Sample Size in Meta-Analysis: A Simulation Study.
Sanchez-Meca, Julio; Marin-Martinez, Fulgencio
Educational and Psychological Measurement, v58 n2 p211-20 Apr 1998
The bias and relative efficiency of two alternative estimators of optimal weights in meta-analysis were assessed through Monte Carlo simulation, defining the standardized mean differences as the effect-size index. The estimator proposed by L. Hedges and I. Olkin (1985) was more efficient than that of J. Hunter and F. Schmidt (1990). (SLD)
