Estimation in meta-analyses of response ratios

Table 2 Point and confidence-interval estimates for τ² and λ in meta-analysis of the effect of the addition of a female cue on female choice; FE is fixed-effect model, and RE is random-effects model. The heterogeneity parameter is τ². L and U denote the lower and upper limits of the 95% confidence intervals
