Hi everyone,
I am running a PLS regression and try to select the parameters with lowest MSE, after cross validating, in order to produce a forecasts. Is there any way to retrieve this vector of parameters?
a = randn(100,5); a = zscore(a);
b = randn(100,1); b = zscore(b);
[XL,yl,XS,YS,beta,pctVar,mse,stats] = plsregress(a,b,5,'CV',10);
forecast = [1 a(end,:)]*beta;
But I am not quite sure if these parameters are the optimal.
