Compute Effective Sample Size for Meta-Analysis

Computes the effective sample size based on the heterogeneity estimate. This is useful for understanding the impact of between-study heterogeneity.

Usage

meta_effective_n(v, tau2)

Arguments

v

Numeric vector of within-study variances

tau2

Numeric scalar; between-study variance (tau-squared)

Value

Numeric scalar; effective sample size
