Sampling the posterior ###################### Once the `prior`, `data`, and `forward` data structures have been defined, the associated a posteriori probability can be sampled using [the extended rejection sampler](/chapSampling/chapSampling_rejection.md) and [the extended Metropolis sampler](/chapSampling/chapSampling_metropolis.md). If the inverse problem is linear and Gaussian it can be solved using [linear least squares](/chapSampling/linear-least-squares.md) inversion. .. toctree:: :maxdepth: 1 :caption: Contents: sippi_rejection sippi_metropolis linear-least-squares
