Hi all. I'm reading the example of how to use partial least squares (https://www.mathworks.com/help/stats/examples/partial-least-squares-regression-and-principal-components-regression.html) But I have a question, if I divide the y-data as
y_train = y(1:50);
y_test = y(51:end);
X_train = X(1:50,:);
X_test = X(51:end,:);
and I follow the exmaple by doing
[Xloadings,Yloadings,Xscores,Yscores,betaPLS] = plsregress(X_train,y_train,2);
How can I use this information in order to make predictions for the test data?
