On the profile likelihood

WebThe profile likelihood is of special use, when analyzing the identifiability of the maximum likelihood estimate (MLE) of the model parameters, but also when deriving confidence … 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.

Web12 de abr. de 2013 · The parameter profile likelihood yields the dependency of the likelihood on a single parameter component. This idea can be generalized by a more general constraint optimization of the likelihood, i.e. instead of fixing a single parameter component like in Eqn 6, a constraint for a prediction F is introduced [ 15, 16].
