WebbPLS actually extracts two sets of scores, one set for X and another set for Y. We write these scores for each space as: t a = X a w a for the X -space u a = Y a c a for the Y -space The … WebbPLS has some advantages over covariance-based approaches. First, covariance-based approaches yield very unreliable results for theory building studies, called factor …
