Power improvement. Left panel: power improvement in using
compared to K
i when n = 8, δ = 0.2 as a function of the CV in K
i for the 66 studies of Table
2. Right panel: scatter plot estimates of the sample size required to reach 80% statistical power as a function of the CV in K
i. The power curve for K
i is shown in black and for
, in blue. The parameter values and power improvement of the three simulation settings S1, S2, and S3 are depicted for reference in each plot.
