In the last decade there have been considerable progress in the
analysis of human EEG. However, if one examines the methods
currently being used for spectral analysis, many of them are based
on two important assumptions: the signal is stationary (in the
wide-sense) and infinite in length. <br>
<br>
First, what is the recommended test for stationarity of EEG signals?<br>
Second, where can one find a list of spectral methods that are <b>not
based on stationarity and finiteness</b>. <br>
Third, is it possible to rank the plethora of spectral methods in
order of being "nearest" to handling signals that are nonstationary
and finite in length?<br>
<br>
Best regards!<br>
