This article presents an open source Matlab program, the ERP PCA (EP) Toolkit, for facilitating the multivariate decomposition and analysis of event-related potential data. This program is intended to supplement existing ERP analysis programs by providing functions for conducting artifact correction, robust averaging, referencing and baseline correction, data editing and visualization, principal components analysis, and robust inferential statistical analysis. This program subserves three major goals: (1) optimizing analysis of noisy data, such as clinical or developmental; (2) facilitating the multivariate decomposition of ERP data into its constituent components; (3) increasing the transparency of analysis operations by providing direct visualization of the corresponding waveforms.
本文介绍了一个开源的 Matlab 程序，即事件相关电位 PCA（EP）工具包，用于促进事件相关电位数据的多元分解和分析。该程序旨在通过提供用于进行伪影校正、稳健平均、参考和基线校正、数据编辑和可视化、主成分分析以及稳健推理统计分析的功能，来补充现有的 ERP 分析程序。该程序有三个主要目标：（1）优化对噪声数据的分析，例如临床或发展数据；（2）通过将 ERP 数据分解为其组成成分，促进多元分解；（3）通过直接可视化相应的波形，提高分析操作的透明度。
