 ==== 2014-07-30: New Version Out (1.9-4) ====
-Quite excited to release a new version of the metafor package (see the full changelog [[:updates_old#changes_in_version_19-4_2014-07-30|here]]). Aside from some minor improvements and bug fixes, the most important addition is the generalized Q-statistic estimator for the amount of (residual) heterogeneity (i.e., $\tau^2$) in random- and mixed-effects models. This is a generalization of the DerSimonian and Laird (DL) and the Hedges (HE) estimators and requires specification of user-defined weights (with the DL estimator corresponding to inverse sampling variance weights and the HE estimator to unit weights). When using this estimator, one can also obtain corresponding confidence intervals for $\tau^2$ based on the exact distributional properties of the estimator (based on Dan Jackson's excellent work).
