tau2_approximation {POMADE}

Between-Study Variance Approximation Function

Description

Rough approximation of the between-study variance based on assumption about the typical sample size of studies included in the synthesis

Usage

tau2_approximation(sample_size = 100, es, df_minus2 = TRUE)

Arguments

sample_size

Typical sample size of studies

es

Smallest effect size of practical concern

df_minus2

If degrees of freedom should be df-2 or just df

Value

A tibble with small, medium, and large magnitudes of tau2

Examples

tau2_approximation(
sample_size = 50,
es = 0.1,
df_minus2 = TRUE
)
