I'm grateful for your kind help. I've clearly got the idea and am relieved. As for question 1, the value of mgcv.conv$rms is small (less than 1.E-5 while GCV being around 1). For question 2, as I don't have other reasons to doubt the linearity, I guess the result is OK. Sincerely, Ariyo 2007/1

Dear all, I'm trying to fit a pure additive model of the following formula : fit <- gam(y~x1+te(x2, x3, bs="cr")) ,with the smoothing parameter estimation method "magic"(default). Regarding this, I have two questions : Question 1 : In some cases the value of "mgcv.conv$fully.converged" becomes "
