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 Web2 de set. de 2016 · Thereby, the profile likelihood provides the range of parameter values supported by the available measurement data. The re-optimisation of other parameters during the profile likelihood calculation is crucial to probe the non-linear relationships between parameters, which are key for discovering suitable model reductions later in the …
