* sampling the ensemble posterior (using an MCMC sampler if the likelihood is fit directly), conditioned on the data-vector, to obtain parameter constraints on the parameters of a physical model, $\boldsymbol{\pi}$.

`sbiax` is a code for implementing each of these steps. The code allows for Neural Likelihood Estimation [@papamakarios; @delfi] and Neural Posterior Estimation [@npe].
