Hi(adsbygoogle = window.adsbygoogle || []).push({});

I like to fit in Mathematica using NonlinearModelFit. When I look at the fitted parameters, there is an entry called "P-value". Here is what it means: "The p-value is the probability of observing a t-statistic at least as far from 0 as the one obtained.". I'm not quite sure what this means. Is it something like chi-square?

Best,

Niles.
