AI总结:

研究通过模拟评估四种似然自由推断方法(MLE、NBE、EOT和AW-NBE)在重尾或离散数据等结构特征下的性能,强调在极端和离散数据下谨慎选择评估工具的重要性。

摘要:

基于模拟的推断(SBI)已成为参数估计中越来越重要的框架,适用于模拟可行但似然评估不可用或成本高昂的情况。虽然最近的工作引入了基准框架来比较似然自由方法,但这些研究通常不考虑重尾或离散性等结构特征。在本文中,我们研究了似然自由推断方法的性能如何依赖于这些结构属性。我们考虑了四种方法:MLE、NBE、EOT和AW-NBE,并通过模拟进行评估。这项研究强调了在存在极端和离散数据的情况下,谨慎选择评估工具的重要性。

英文摘要:

Simulation-based inference (SBI) has become an increasingly important framework for parameter estimation in models for which simulation is feasible, including cases where likelihood evaluation is unavailable or costly. While recent work has introduced benchmark frameworks to compare likelihood-free methods, these studies often do not account for structural features such as heavy-tails or discreteness. In this article, we investigate how the performance of likelihood-free inference methods depends on these structural properties. We consider four approaches: MLE, NBE, EOT and AW--NBE and evaluate them using simulations. This study highlights the importance of carefully selecting evaluation tools in the presence of extremes and discrete data.
