NettetThe 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. The thing is, the normal distribution has a particular shape — i.e. symmetrical. NettetWe derive the asymptotic limiting distribution of the mul-tivariate PLE, for all values of the true parameter. In particular ... asymptotic distribution of the MLE, which shows that the asymptotic variance of both the estimators is the same.

Nettet12. aug. 2024 · Thus, the limiting distributions of α ˜ T and κ ˜ T are not normal. In particular, the asymptotic distribution of κ ˜ T is a Dickey–Fuller–Phillips-type distribution with the rate of convergence being T. Hence, when κ = 0 is unknown, the value of α plays an important role in the study of asymptotic laws for the MLE.
