dr_heterogeneity R Documentation
Classical heterogeneity diagnostics and design-indexed summaries
Description
Reports the classical fixed-effect residual Q statistic and I^2
alongside the fitted design-indexed scale parameters. Unlike version 0.1.0,
this function does not return a design-explained variance decomposition;
that quantity was not identified by the model and has been replaced by
dr_scale_attenuation.
Usage
dr_heterogeneity(object)
Arguments
object
A fitted drmeta object.
Value
A list with components Q, df, p, I2,
tau0sq, gamma, attenuation_observed, and
tau2_by_study.
Examples
path <- system.file("extdata", "bcg_design_robustness.csv", package = "drmeta")
bcg <- utils::read.csv(path)
fit <- drmeta(yi = bcg[["yi"]], vi = bcg[["vi"]], dr = bcg[["dr"]])
dr_heterogeneity(fit)
