Your questions is pretty opaque. Please adhere to the posting guide. Provide
a self-contained (!) example (i.e., code) that reproduces your problem.
Generally, you would predict like this:
where you can substitute any vector of values for x
> I have 5 GAMs ( model1, model2, model3, model4 and model5)
> Before I use some data X(predictor -January to June data) to form a
> equation and calculate the expected value of Y (predictand -January to
> June). After variable selection, GAMs (Model 1)were bulit up! R-square
> NOW, I want to use new X'( predictor -July - December data) and put into
> Model 1, then get the expected value of Y' (predictand-July -December)
> I used mcgv package, what should I do now?
