Convert Various Meta-Analysis Heterogeneity Measures

Description

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.

Published meta–analyses often only provide a subset of the heterogeneity measures first described in Higgins and Thompson (2002). This package provides a way of converting between some of them. It allows for the input of I2, Q or p and outputs Q, H, I2, and confidence intervals for them. It also contains the data used as examples in that original article.
