SAMPLS R implementation : pbm with algorithm application
...atrix of
responses, h the number of latent variables extracted
XT is for X matrix transposed
x* is for the quantities for one sample (y* is the response
predicted from the model derived; i used one to test my R traduction
compared to the R pls module )
Calculate the covariance matrix C=XXT and c*=Xx* for
prediction
y is centered and become y1
