WebTo get what you want, you can use something like optim to fit the curve to your data. The following code will use nonlinear least-squares to find the three parameters giving the best-fitting gaussian curve: m is the gaussian mean, s is the standard deviation, and k is an arbitrary scaling parameter (since the gaussian density is constrained to ... WebMar 26, 2014 · The data is a distribution of signal over a rate (i.e. Y - Signal magnitude, X - time). I am trying to fit the distribution by transforming the function for the normal distribution PDF so that I can use it in a least squares fit of the data. This is what I do: I change: f (x) = 1/ (s*sqrt (2*pi)) * exp ( - ( (X - m).^2)./ (2*s^2) ); to:
