 Again, the results match the findings from Berkey et al. (1995): The residual amount of heterogeneity is now $\hat{\tau}^2 = 0.157$ and the estimated model is $log(RR) = -0.6303 - 0.0268 (x - 33.46)$, where $x$ is the distance from the equator (in degrees latitude). The standard errors of the model coefficients are $SE[b_0] = 0.1591$ and $SE[b_1] = 0.0110$. Again, the results match the findings from Berkey et al.
