Design

A typical inference with SBI occurs with

• fitting a density estimator to a set of simulations and parameters $(\xi, \pi)$ that may be compressed to summary statistics,
• the measurement of a datavector $\hat{\xi}$,
• the sampling of a posterior $p(\pi|\hat{\xi})$ conditioned on the measurement $\hat{\xi}$.

sbiax is designed to perform such an inference.
