PTA3 with penalisation for time and Space on an fMRI data
The same analysis using a identity metric but penalisation for time and space -the time components smoother is the same as before and the space smooter is a 2D wavelet approximation using wavethresh from R- gives for the first Principal tensor:
summary of the decomposition
The first PT is very similar to the one obtained when penalising only on time. Notheless apart from obtaining a smoother space component the subject component is slightly different.
