comment How well does my function fit data?
Antonio, Take a look at :reference.wolfram.com/language/tutorial/… and also reference.wolfram.com/language/ref/NonlinearModelFit.html "AdjustedRSquared" will tell you how much overlapping (shared or common variance) there is between your data and your model. It is a measure of goodness of fit. You can also obtain confidence intervals.

comment How well does my function fit data?
Antonio, Modeling can tell us how closely the data fit the function, but it does not, and cannot, tell us "whether the function is correct or not". In that sense, models are approximations. Furthermore, there will inevitably be conditions under which the model "breaks down", i.e. ceases to provide a satisfactory description of at least some aspects of the phenomenon.
