I think you can used matlab software, it is simple to use by plsregress function. The weblink: https://cn.mathworks.com/help/stats/plsregress.html. I hope that it will help you!
Thanks Xiuliang,
Can you please send a dummy example of inputs (i.e. X,Y and ncomp) so that i can use it in matlab expression i.e. [XL,YL] = plsregress(X,Y,ncomp) and understand the concept also. If you can please take an example of hyperspectral reflectance values for chlorophyll estimation.
I will be really thankful for you kind help.
X is vegetion index, Y is chlorophyll content, ncomp is the number of principle components, which denpends on your aims.
This is a example: which is included in matlab software.
load spectra
X = NIR;
y = octane;
[XL,yl,XS,YS,beta,PCTVAR] = plsregress(X,y,10);
Thank you so much... i will go through the problem... If got any problem i will again request you for help...
