Hi,
Is there any way I can see how exactly the prediction equation is
constructed in the example below? I'd like to be able to replicate the
predictions from the fitted gam object as given by the predict.gam method in
the package "mgcv".
library(mgcv)
data(trees)
ct1 <- gam(Volume ~ s(Height) + s(Girth),
family=Gamma(link=log), data=trees)
summary(ct1)
newdata <- cbind(Girth=mean(trees$Girth),
Height=mean(trees$Height), Volume=mean(mean(trees$Volume)))
pred <- predict(ct1,as.data.frame(newdata),type="response")
pred
Thanks in advance,
Lars.
