[Faster-eeg-list] outlier analysis

[Brian R. <bri...@nc...>]

Hi All,

We're using FASTER to analyze data from control participants and 
patients with schizophrenia.  We have two auditory N1 conditions.  I 
read about the application of FASTER to mmn data from Parkinson's 
subjects.  I am interested in recommendations for running the grand 
average outlier test in multi-condition, multi-group studies.  Would you 
put all subjects and conditions in one test, run a separate test for 
each condition, or run separate tests for every condition and group?  In 
a normal ERP peak analysis, we would look for outliers separately in 
each group, but in that case we expect group differences.  With measures 
such as amplitude range, variance, and channel deviation, I don't really 
know what to expect yet.  I am interested in what others think or have 
tried.

Thanks,
Brian
