Nyström核 Stein 差异检验加速拟合优度检验

研究人员开发了 Nyström 核 Stein 差异 (KSD) 检验,显著提高了拟合优度检验的效率。传统的 KSD 估计量具有二次运行时间和计算上难以处理的零分布,通常需要引导。这种新方法利用 Nyström 方法加速 KSD 估计,同时保持统计准确性和渐近水平和局部一致性等关键特性。数值结果表明,Nyström 加速方法在性能上与原始方法相当,但运行时间大大减少。 AI

    Nyström核石差异检验

    Kernel Stein discrepancy (KSD) is among the most popular goodness-of-fit (GoF) measures on general domains with a large number of successful deployments. One of the main applications of KSD is in constructing powerful GoF tests. However, tests relying on the classical U-/V-statis…
