Fit the normal distribution
WebHere’s the normal distribution: We 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) WebJun 6, 2024 · Let’s draw random samples from a normal (Gaussian) distribution using the NumPy module and then fit different distributions to see whether the fitter is able to identify the distribution. 2.1 ...
