MBPLS is the prototypical component based supervised multiblock method.
It was originally formulated as a twolevel method with a blocklevel and a superlevel,
but it was later discovered that it could be expressed as an ordinary PLS on concatenated
weighted X blocks followed by a simple loop for calculating blocklevel loading weights,
loadings and scores. This implementation uses the plsr
function on the
scaled input blocks (1/sqrt(ncol)) enabling all summaries and plots from the pls
package.
