Power and Type 1 error of hypothesis test on simulated data.

For each combination of coverage and purity, results are shown for trees with node counts from three to eight. Each curve was computed by taking the mean over all instances and all replicates for each node count. Curves with circular marks show power and curves with triangular marks show Type 1 error. Transparent coloring indicates ±1SE. Dotted line indicates power = 0.8.
