WebI'm trying to fit a Gaussian for my data (which is already a rough gaussian). I've already taken the advice of those here and tried curve_fit and leastsq but I think that I'm missing something more fundamental (in that I have no idea how to use the command). Here's a … WebNormal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. Where: μ is the mean of samples in distribution or continuous location parameter. σ is …
