Re: [R] p-value for non linear model

Tatiana: It sounds like you are in way over your head statistically. This is not a statistics tutorial site (though sometimes good folks do help witjh this). I suggest you try http://stats.stackexchange.com/ . Better yet, work with your local statistician. Cheers, Bert On Thu, Sep 15, 2011 at 6

[R] p-value for non linear model

Hello, I want to understand how to tell if a model is significant. For example I have vectX1 and vectY1. I seek first what model is best suited for my vectors and then I want to know if my result is significant. I'am doing like this: model1 <- lm(vectY1 ~ vectX1, data= d), model2 <- nls(vectY1
