GAM without intercept
Hi everybody,
I am trying to fit a GAM model without intercept using library mgcv.
However, the result has nothing to do with the observed data. In fact
the predicted points are far from the predicted points obtained from the
model with intercept. For example:
#First I generate some simulated data:
library(mgcv)
x<-seq(0,10,length=100)
y<-x^2+rnorm(100)
#then I fit a gam model with
