Figure 2:

Receiver operating characteristic and Precision-recall curves from the simulation study. (a) For data simulated under the “true” model, and the parameters for the analysis varied. We added a small amount of random “jitter” to the curves since they are hard to distinguish otherwise. (b) For data simulated under a model where the admixture proportion is 1.5% and analyzed using the same model and the “true” model. (c) For data simulated under a model where the admixture proportion is 6% and analyzed using the same model and the “true” model.
