check.k function in mgcv packages
Hi,everyone,
I am studying the generalized additive model and employ the package 'mgcv'
developed by professor Wood.
However,I can not understand the example listed in check.in function.
For example,
library(mgcv)
set.seed(1)
dat <- gamSim(1,n=400,scale=2)
## fit a GAM with quite low `k'
b<-gam(y~s(x0,k=6)+s(x1,k=6)+s(x2,k=6)+s(x3,k=6),data=dat)
plot(b,pages=1,residuals=TRUE)
