The dimensionality effect is avoided by the use of sufficient statistics in event probability estimators realised by importance sampling. If the system function is not a sufficient statistic, an approach is proposed to reduce the dimensionality effect in the estimators. Simulation results of false‐alarm probability estimations, applied to radar detection, confirm a clear concordance with the theoretical results.
