In statistics, maximum likelihood estimation (MLE) is a method of estimating the parameters of an assumed probability distribution, given some observed data. This is achieved by maximizing a likelihood function so that, under the assumed statistical model, the observed data is most probable. The … Meer weergeven We model a set of observations as a random sample from an unknown joint probability distribution which is expressed in terms of a set of parameters. The goal of maximum likelihood estimation is to determine … Meer weergeven A maximum likelihood estimator is an extremum estimator obtained by maximizing, as a function of θ, the objective function $${\displaystyle {\widehat {\ell \,}}(\theta \,;x)}$$. If the data are independent and identically distributed, then we have Meer weergeven It may be the case that variables are correlated, that is, not independent. Two random variables $${\displaystyle y_{1}}$$ and $${\displaystyle y_{2}}$$ are independent … Meer weergeven Early users of maximum likelihood were Carl Friedrich Gauss, Pierre-Simon Laplace, Thorvald N.
