Dear List
I am trying to use gam function in mgcv 17.26. I have a big data set of
about 40,000 data points. Every time that I run it ,it results in GCV score
of "0"
Family: gaussian
Link function: identity
Formula:
D ~ s(Ghazl_res) + s(Depth)
Estimated degrees of freedom:
3.77 2.91 total = 7.68
GCV score: 0
Plotting the curves of the predictor variables also gives a straight
horizontal line along the zero value of the y axis. I really couldn't
interpret whats going wrong. Appreciate it if anyone can comment
