So the gam function itself tunes my degrees of freedom right? The default smoothing function is the "thin plate" regression spline. So basically Caret is just doing a ridge regression for me, meaning reducing the unimportant variables to almost zero? And it uses the method gcv.cp to find the "best" amount of knots for my splines? | |
