Posterior predictive checks for the BROKEN POWER LAW + 2 PEAKS model. The orange CDFs denote predictions of O4a observations from the BROKEN POWER LAW + 2 PEAKS model fit to GWTC-3.0 data, whereas the blue CDFs denote O4a observations. The predicted and observed curves match within their 90% credible regions, indicating that the BROKEN POWER LAW + 2 PEAKS model performs well at describing held-out data.
