Dear R users,
I am working on a simple mathematical model made of two ordinary differential equations: dx/dt=-mx-d1(x-c) dy/dt=mx-d2y I would like to fit this model to my data and estimate the corresponding parameters. The thing is I only have observed data for y, x is unknown. Is it possible to do this in R? Thank you for your help Fanny [[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.
