Hi,
I am a brand new user of R and I am trying to use the gam procedure with the
package mgcv. I did a bit of my homework by consulting the R-manual, as well as
the mgcv manual written by Simon Wood. I admit it was just a few hours, but
what I am trying to do is really basic. Essentially, what I am trying to do is
to generate the fitted values after the execution of the gam procedure and
export them into Excel.
Here is my program:
ABC<- read.table("Incidence Data.csv", header=TRUE, sep=",")
probably the next three lines can be omitted if you just say:
fit <- gam(incidence~te(age,birthyear), data=ABC, family=poisson, fit=TRUE)
incidence<- ABC[,1]
age<- ABC[,2]
birthyear<- ABC[,3]
fit<-gam(incidence~te(age,birthyear), family=poisson, fit=TRUE)
All this works. Now, how can I see the fitted values and copy them back to
Excel?
As for most fitted models, you can get
Fitted values:
predict(fit)
Coefficients:
coef(fit)
etc.

Thank you very much,
