cvh2_ml: cvh2_ml

Description

CVH2 for mulilevel meta-analytic models, based on Yang et al. (2023). Under multilevel models, we can have multiple CVH2. TODO - we need to cite original CVH2 paper

Usage

cvh2_ml(model, boot = NULL)

Value

A data frame containing all the model results including mean effect size estimate, confidence, and prediction intervals

Arguments

model

Model object of class rma.mv or rma. Currently only model objects using the mods argument work (e.g., mod = ~1).

boot

Number of simulations to run to produce 95 percent confidence intervals for I2. Default is NULL, where only the point estimate is provided.
