hello,
my problem is like this: now after processing the varibles, the remaining
160 varibles(independent) and a dependent y. when I used PLS method, with 10
components, the good r2 can be obtained. but I donot know how can I express
my equation with the less varibles and the y. It is better to use less
indepent varibles. that is how can I select my indepent varibles. Maybe
GA is good method, but now I donot gasp it. and can you give me more good
varibles selection's methods. and In R, which method can be used to select
the potent varibles . and using the selected varibles to model a equation
with higher r2, q2,and less RMSP.
thank you!
