Fmri analysis methods
WebMost methods used for fMRI analysis assume that observations are independent and that the noise can be treated as white gaussian noise. These assumptions are usually not true but it is difficult to assess how severely these assumptions are violated and what are their practical consequences. http://web.mit.edu/swg/ImagingPubs/Smoothing/skudlarski_roc_analysis.pdf
