[R] plotting gam plots from mgcv package
Dear List I am fitting some GAM models using the package mgcv. When plotting the response curves of the individual predictors using gam.plot I get a dotted line of the confidence interval around the fitted line. Does anybody know a way to make these as grey area around the fitted lined instead of the dotted lines/ Thanks in advance Regards *BCTS* GIS *Hossameldin ELALKAMY, **MPhill., PhD.* *GIS Analyst * BC Timber Sales | Prince George Ministry of Forests, Lands and Natural Resource Operations P. 250.614.7521 C. 778.896.3229 | 2000 Ospika Blvd. PG, BC., V2N 4W5 Webpage <https://www.for.gov.bc.ca/bcts/> | GIS Requests <https://spc-bcts.gov.bc.ca/BCTSNGG/SitePages/TPG%20Prince%20George.aspx> | Profile <https://www.linkedin.com/in/husam-el-alqamy-82212b6a/> [image: BC FLNRO] [[alternative HTML version deleted]] __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
[R] GCV=0 in gam fitting
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 Husam El Alqamy, B.Sc, M.Phil.
