2014-02-06 Thread Husam El Alqamy
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 2.9
