PLS think twice about partial least squares
One of the great things about writing a statistics book was finding an excuse to read about dozens of topics that I knew a little about but hadn't got around to studying in depth. Even so, there were a number of topics I ended up missing out on completely (apparently once the book gets to over a 900 pages or so they make you leave stuff out). One of those topics is partial least squares (PLS).
I knew a bit about the technique (but it turns out even less than I thought). I recently came across an excellent paper on partial least squares by Mikko Rönkkö, Cameron McIntosh and John Antonakis. The main thrust of the paper is simple - partial least squares is a widely used technique outside psychology, and it has been suggested should be more widely used within psychology.
