in mgcv gam() works! --- Tristan Kosciuch Stewart Biology Building, McGill University 1205 Dr Penfield Ave, Montreal QC H3A 1B1 ________________________________ From: Bert Gunter <bgunter.4...@gmail.com> Sent: Friday, April 17, 2020 7:28 PM To: Tristan Kosciuch <tristan.kosci...@mail.mcgill.ca> Cc: r-help@R-project.org <r-help@r-project.org> Subject: Re: [R] Multi response GAM https://cran.r-project.org/web/views/Multivariate.html https://cran.r-project.org/web/views/Environmetrics.html https://cran.r-project.org/web/views/TimeSeries.html Also search on "multiresponse GAM" or similar at rseek.org<http://rseek.org>. This brought up what looked to me like useful hits. And of course, don't forget Mama Google.

I have 3 diet classes as my response variables; fish 1, fish 2, and invertebrates. The response variables are correlated, declines in invert consumption ~ increase in fish consumption. Any advice on how to handle this would be appreciated. I would like to use GAMs as my time series shows fluctuations that could only be fit by high order polynomials if I were to use a linear model, but open to suggestions. Thank you for your time. P.s. I will be comparing the fit of the time series GAM with a model based on other predictors, with a training and validation split for my data. --- Tristan Kosciuch Stewart Biology Building, McGill University 1205 Dr Penfield Ave, Montreal QC H3A 1B1 [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org<mailto: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.
