 To examine the utility of this method, we examined 513,792 models based on both simulated and real samples. Figure 1 depicts the accuracy of our method across our included data sets. More information on nQuack's implementation of nQuire can be found on [our pkgdown site](https://mlgaynor.com/nQuack/articles/ModelOptions.html) and in the [Appendix S1](https://www.doi.org/10.1002/aps3.11606). In Figure 1, the simplified version of nQuack only classifies samples as diploid or polyploid - though this is not ideal, it is accurate!
