A statistical approach to evaluate evoked potentials (EPs), consisting of three stages in procedure, was proposed with an application to study on postictal changes of visually evoked potentials (VEPs). At the first step, time series data of EPs were reduced by the means of using an autoregressive (AR) model. In this way, EPs were described in terms of AR coefficient vectors. Then statistical distances which are well known as the Mahalanobis' distances were determined as a scale for dissimilarity between patterns of EPs. At the third stage, a retrospective classification through a numerical taxonomy based on similarity of patterns was demonstrated. This procedure will tell us some standards for future experiments as well as an integrative insight of results from present experiment. By the above method, it was suggested that there may be two different processes in postictal recovery of kindled cats.
提出了一种评估诱发电位（EPs）的统计方法，该方法在程序上包括三个阶段，并应用于研究视觉诱发电位（VEPs）发作后的变化。第一步，通过使用自回归（AR）模型来减少EPs的时间序列数据。通过这种方式，用AR系数向量来描述EPs。然后，确定众所周知的马氏距离作为EPs模式之间差异的尺度。在第三阶段，展示了通过基于模式相似性的数值分类法进行的回顾性分类。这个程序将告诉我们未来实验的一些标准以及对当前实验结果的综合洞察。通过上述方法，有人提出在点燃猫的发作后恢复过程中可能存在两个不同的过程。
