WebLikelihood L(Y,θ) or [Y θ] the conditional density of the data given the parameters. Assume that you know the parameters exactly, what is the distribution of the data? This is called a likelihood because for a given pair of data and parameters it registers how ‘likely’ is the data. 4. E.g. In many cases, the likelihood is a function of more than one parameter but interest focuses on the estimation of only one, or at most a few of them, with the others being considered as nuisance parameters. Several alternative approaches have been developed to eliminate such nuisance parameters, so that a likelihood can be written as a function of only the parameter (or parameters) of interest: the main approaches are profile, conditional, and marginal likelihoods. These approa…
