dat.higgins02

The package contains the following dataset: <code>higgins02</code>.

datasets

Published meta-analyses routinely present one of the
measures of heterogeneity introduced in Higgins and Thompson
(2002) <doi:10.1002/sim.1186>. For critiquing articles
it is often better to convert to another of
those measures. Some
conversions are provided here and confidence intervals are also
available.
