adapt_import


Importance sampling option for probability refinement

Specification

Alias: none

Argument(s): none

Description

adapt_import centers a sampling density at one of the initial LHS samples identified in the failure region. It then generates the importance samples, weights them by their probability of occurence given the original density, and calculates the required probability (CDF or CCDF level). This continues iteratively until the failure probability estimate converges.
