Re: [R] define a new family (and a new link function) for gam in gam package
Dear Simon, I want a simple generalised additive model for regression which I can customise (force /define a certain basis, certain order for the splines, knots vector, generating new link functions, and force the regression through 0,0). What do you suggest?
