单侧化准备电位启始时间点的测算:刀切法

Measurement of the Onset of LRP : Jackknife

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。

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 rel- ative to the previous single subject method. This paper introduced the statistics principles and basic process of jack- knife, compared the differences with single subject procedures, and prospected the development of this method in future.
