"# Simulation-based Calibration in SBI\n",
"\n",
"After a density estimator has been trained with simulated data to obtain a posterior, the estimator should be made subject to several diagnostic tests, before being used for inference given the actual observed data. *Posterior Predictive Checks* (see tutorial 12) provide one way to \"critique\" a trained estimator via its predictive performance. Another important approach to such diagnostics is simulation-based calibration as reported by [Talts et al, 2018](https://arxiv.org/abs/1804.06788).\n",

Another important approach to such diagnostics is simulation-based calibration as developed by [Cook et al, 2006](https://www.tandfonline.com/doi/abs/10.1198/106186006X136976) and [Talts et al, 2018](https://arxiv.org/abs/1804.06788).\n",

"**Simulation-based calibration** (SBC) provides a (qualitative) view and a quantitive measure to check, whether the uncertainties of the posterior are balanced, i.e., neither over-confident nor under-confident. As such, SBC can be viewed as a necessary condition (but not sufficient) for a valid inference algorithm: If SBC checks fail, this tells you that your inference is invalid. If SBC checks pass, this is no guarantee that the posterior estimation is working."
