A collection of functions for conducting a meta-analysis with mean differences data. It uses recommended procedures as described in The Handbook of Research Synthesis and Meta-Analysis (Cooper, Hedges, & Valentine, 2009).
o Added new datasets and updated documentation
o agg() now can (1) work with both pooled and control grp SD, (2) handle various correlations structures between within-study outcomes, including a fixed correlation and a correlation matrix to allow different correlations between outcome types, and (3) now includes several procedures for handling dependencies, including the Gleser and Olkin(1994) and Borenstein, et al (2009) procedures.
o Several new data sets. o Minor edits to a few functions. o Documentation changed accordingly.
