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
