Working through the R archives and webspace, I've mostly proved to myself that I don't know enough about what statisticians call "Curve Fitting" to even begin translating the basics. I'm a sysadmin, and have collected a variety of measurements of my systems, and I can draw pretty pictures in R showing what has happened. People are happy, customers feel empowered. Whee! Now, I want to take my corpus of data and make a prediction based on it; In statistics-moron speak, I want to draw a line or a simple curve across my extant graph, and figure out where the predictive curve passes threshold 'T', and then graph that too. I thought I'd be telling R something like: - I think this is exponential. Here's the data. Give me the best function you can come up with, and tell me "how good" the fit is. - I think this is quadratic. Here's the data. Give me the best function you can come up with, and tell me "how good" the fit is. Can someone point me at a spot in the docs which might be suitable for my level of ignorance? - Allen S. Rout

With the help of the R project statistical engine (a remarkable piece of software), the user will be able to receive emails such as: "the disk on server S... is likely to become full in 3 weeks". The statistical model will be automatically determined by moodss in the new predictor viewer, from traditional models (ARIMA, ...) and neural networks... Expect the new release by the end of 2005. Unfortunately, that'll take a few months... - -- Jean-Luc Fontaine http://jfontain.free.fr/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFDeLvGkG/MMvcT1qQRAtZUAKCYlqJP77sD4yeS747uvoNrtljHiwCfebkd w+uE4Ip++2oabUWJjFqoZU4=hCLa -----END PGP SIGNATURE-----
