[Christopher Robert <chris_robert@hksphd.harvard.edu>]

Thanks to Kit Baum, -avg_effect- is now available from SSC.

avg_effect yvar1 yvar2 [ yvar3 ... ] [ if ], x(varlist)
effectvar(varlist) controltest(string) [ options ]

avg_effect follows Kling et al. (2004) and Clingingsmith et al. (2009)
in calculating average (standardized) effect size using the
seemingly-unrelated regression framework to account for covariance
across estimates.

To install, type -ssc install avg_effect-.
