So, i have a dataset which behaviour could be approached by the power law: $ $ N(x)= a – bx^{-1/c} $ $ So i am doing this to get the regression: nlm = NonlinearModelFit[data, a – b*x^(-1/c), {{a, 0}, {b, 0}, {c,2}}, x, MaxIterations -> \[Infinity]] So i get the following result: Then i getRead more
