Description Functions and data included in the package Author(s) References
The hetmeta
package contains functions useful to assess the presence and to quantifying
the impact of statistical heterogeneity.
Several measures of heterogeneity are implemented in the hetmeta
function.
All the functions in the packages requires a meta-analytic model of class rma.uni
that can be easily obtained using the metafor
package.
See metafor-package
for a comprehensive and detailed description.
The main function is hetmeta
, which calculates the measures of heterogeneity
in an object of class "hetmeta
" (see hetmetaObject
). The methods
print.hetmeta
and confint.hetmeta
defines function for
printing results and deriving confidence intervals.
