There is little theory about significance and testing for PLSR (and, I would guess, GPLSR). Many practicioners use Jackknife variance estimates as a basis for significance tests. Note, however, that these variance estimates are known to be biased (in general), and their distribution is (to my knowledge) not known. Any significance deduced from them should therefore be regarede as merely indicators.
