About GAM in R, Need YOUR HELP!
If you use the mgcv package for GAMs, I found this book very helpful: Wood, SN Generalized additive models: An introduction with R CRC Press, 2006 ISBN-13: 9781584884743 --Chris Ryan SUNY Upstate Medical University

I'm beginner in R! I have a lot of problems on R..... I have three questions about GAM 1. What is the function of Gaussian distribution in GAM?(if I choose family is Gaussian) Is it used in the predictand value (Y)? 2. How to plot a graph the gam function? For example: y<-gam(a~s(b),family=gaussian (link=log) ,Data) how to plot x axis is s(b) and y axis is log a??? 3. if I use GAM to create an equation with smoothing function For example: y<-gam(a~s(b)+s(c),family=gaussian (link=log),Data) how to get the coefficient of s(b) , s(c) My final target is getting the GAM equation to predict a, so I need to know how to get the coefficient of equation and how to write the equation!!! As I know, I'm silly to ask these questions. But GAM is very difficult to me. From now on, I need to clear the concept of GAM.
