Techniques to Assess Stationarity and Gaussianity of EEG: An Overview

Often, while analyzing naturally generated signals (such as speech, seismogram, electroencephalogram, etc.), questions of stationarity and Gaussianity (normality) arise. This paper presents a brief literature overview focused on different methods proposed for assessing stationarity and Gaussianity of electroencephalogram (EEG). Summaries of several methods are discussed.
