本文从涉及配对比较的研究中发展了效应量的Glass-type（1976）估计量的分布理论。我们根据Hedges（1981）关于组合独立样本效应量的工作推导出效应量的无偏估计。它表明，研究涉及配对和独立的样本的混合物也可以以这种方式相结合。效应量的近似置信限。该方法是说明使用一个例子，从精神病学研究。
This article develops the distribution theory for a Glass-type (1976) estimator of effect size from studies involving paired comparisons. We derive an unbiased estimator of effect size following Hedges's (1981) work on combining effect sizes from independent samples. It is shown that studies involving mixtures of paired and independent samples can also be combined in this way. Approximate confidence limits for effect size are derived. The method is illustrated using an example from psychiatric research.
