CCL: Svar: CCL: PLS implementation?

 Sent to CCL by: "Niels Johan Christensen" [njc=-=life.ku.dk]
 Hi Joe,
 One option is to implement a PLS algorithm in your favorite programming
 language. The NIPALS PLS algorithm is particularly simple to understand and work
 with (~10 lines of code in Matlab).

 Folks, I would appreciate any pointers to PLS implementations that can
 handle much larger number of X variables as compared to Y (to-be-fit)
 variables.  I recall that PLS was used in 3D QSAR applications because
 of its stability in such cases, but it seems that individual
 implementations differ in how this statement applies to them...
 3D QSAR test sets w/ aligned compounds would also be of use - if
 people are aware of such collections on-line.  But the PLS engine(s)
 are my primary search right now...
 Thanks in advance!
