The estimation method requires that the data are independent and identically distributed (iid). It performs well even when the distribution is asymmetric or censored. EL methods can also handle constraints and prior information on parameters. Art Owen pioneered work in this area with his 1988 paper. pacific law firm.com

WebNov 6, 2024 · At page 128, it writes the maximum log-likelihood estimator and then says it is equivalent to the expectation over the empirical distribution. To obtain a more convenient but equivalent optimization problem, we observe that taking the logarithm of the likelihood does not change its arg max but does conveniently transform a product into a … WebOct 1, 2024 · The empirical likelihood function is maximized by the empirical distribution function L ( F n) = ∏ i = 1 n n − 1, and the empirical likelihood ratio function R ( F) = L ( … pacific law academy stockton ca
