WebWe have two parameters in this distribution, the mean (μ) and the standard deviation (σ). The MLE process will find the best μ and σ so that the distribution fits the data the best it possibly can; this should give you the exact same μ and σ as by using: import numpy as np mu = np.mean (data) sigma = np.mean (data) Given data, of course.
