Abstract: Jacknife is a parameter estimation method proposed by Quenouille, and was applied by Miller in 1998 for the first time in the measurement of the onset of lateralized readiness potential (LRP). Its a new statistical method relative to the previous single subject method. This paper introduced the statistics principles and basic process of jackknife, compared the differences with single subject procedures, and prospected the development of this method in future.

Key words: jackknife, LRP, onset

摘要: 刀切法是统计学家Quenouille提出的一种参数估计方法,由Miller等在1998年首次将刀切法应用在单侧化准备电位(LRP)启始时间点(onset)的测量中。相对于以往单个被试法而言,它是较新的一种统计方法。本文综述了刀切法的统计原理和基本使用过程,并和单个被试法进行了差异比较,最后对这一方法的发展趋势做了展望。
