MCMC design-based non-parametric regression for rare-event. Application to nested risk computations
... The outer Monte Carlo stage samples distributions restricted to {Y ∈ A}. A naive acceptance-rejection on Y fails to be efficient because most of simulations of Y are wasted. Therefore, specific rare-event techniques have ...
