From: Methods for calculating confidence and credible intervals for the residual between-study variance in random effects meta-regression models

Method Estimate Interval
REML 0.042 (0.016, 0.111)
Gen Q ( a i = σ i - 2 ) 0.043 (0.017, 0.139)
Gen Q ( a i = σ i - 1 ) 0.048 (0.018, 0.138)
Paule-Mandel/Q profile 0.049 (0.018, 0.156)
Bayesian 0.050 (0.017, 0.119)
  1. The REML confidence interval for τ 2 is approximate and the Bayesian estimate is the posterior mean.
