help: what are the basis functions in {mgcv}: gam?
If you can't get hold of the book, try appendix A of http://www.maths.bath.ac.uk/~sw283/simon/papers/psm.pdf -- what's described there is the "cr" basis best, Simon

Thanks for Andrew Robinson's suggestion. I am sorry that I have been looking for the book Wood (2006) "Generalized Additive Models: Introduction with R" for a long time in my univerity and book stores, but I failed to find one. I think it may take a long time to buy one from the Internet, and we are required to submit the master thesis soon... Could any one help me if you know other references or have knowledge about this?? I will be very very thankful. Sincerely yours, Olivia oliviax wrote:
I am writing my thesis with the function gam(), with the package {mgcv}.
My command is: gam(y~s(x1,bs="cr")+s(x2, bs="cr")).
I need help to know what are the default basis funcitons for gam. I have
not found any detailed reference for this.
Can anyone help me with this??
