WebInstagram Help Center WebThe likelihood function (often simply called the likelihood) is the joint probability of the observed data viewed as a function of the parameters of a statistical model.. In maximum likelihood estimation, the arg max of the likelihood function serves as a point estimate for , while the Fisher information (often approximated by the likelihood's Hessian matrix) …

WebWe show, through two data examples, that our adjusted likelihood methods also enjoy this property in this more general context. Section 2 of this paper introduces double generalized linear models, in which the mean and the dispersion are modelled simultaneously. The saddle-point approximation and its accuracy is discusses in Section 3.
