[R] Partial Least Squares

[Spencer Graves]

      Did you "read the posting guide! 
http://www.R-project.org/posting-guide.html"?  In particular, did you 
try www.r-project.org -> search -> "R site search" for "partial least 
squares"?  I just got 65 hits for "partial least squares".  Some were 
not relevant, but many were.  I also got 9 hits for "nipals", all of 
which seemed relevant. 

      Also, have you considered "sem" (structural equation modeling)?  
 From what I've heard, partial least squares started out as a solution 
without a clear problem statement, i.e., an algorithm claiming to solve 
a problem but without a clear statement of a probability model for which 
their algorithm produced the (approximate) maximum likelihood or 
Bayesian posterior mode.  Structural equation modeling, by contrast, 
provides the model and problem statement that partial least squares 
seems to try to solve.  I got this impression from reading the PLS 
article in the Encyclopedia of Statistical Sciences. 

      hope this helps.  spencer graves
