See [this vignette](https://easystats.github.io/performance/articles/simulate_residuals.html) and the documentation of `simulate_residuals()` for further details. The above plot suggests that we may have issues with overdispersion and/or zero-inflation. We can check for these problems using `check_overdispersion()` and `check_zeroinflation()`, which will perform statistical tests (based on simulated residuals). These tests can additionally be used beyond the visual inspection.
