Gaussian fit for Python

Question

I\'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 leasts

Answer 1

After losing hours trying to find my error, the problem is your formula:

sigma = sum(y*(x-mean)**2)/n

This previous formula is wrong, the correct formula is the square root of this!;

sqrt(sum(y*(x-mean)**2)/n)

Hope this helps
