On the profile likelihood
Web8 de jun. de 2009 · The profile likelihood of a practically non-identifiable parameter has a minimum, but is not excessing a threshold Δ α for increasing and/or decreasing values of θ i (see Definition 1). In contrast, the profile likelihood of an identifiable parameter exceeds Δ α for both increasing and decreasing values of θ i.

Webis the conditional maximum-likelihood estimator of θ and consequently is a function of μ itself. The denominator, instead, is maximized in an unconstrained way, thus μˆand θˆare the true maximum likelihood estimators. Hence, by definition, the profile likelihood ratio is comprised between 1, when the hypothesized μ coincides WebThe Profile Likelihood 3.1 The Profile Likelihood 3.1.1 The method of profiling Let us suppose that the unknown parameters can be partitioned as 0 =(0,0), where are the p …
WebThis 'profile likelihood' method reduces 1(0) to a function of a single parameter of interest by treating the others as nuisance parameters and maximising over them. Specifically, for , = Oj the parameter of interest, let us denote the families of parallel hyperplanes in parameter space {0 E 0:0- = B} by 0j(f). Then 7j(l) = max 1(0) (1) 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 …
