Canonical Likelihoods: A New Likelihood Treatment of Nuisance Parameters
典范似然:处理干扰参数的新似然方法
A new approach to the likelihood analysis of models with nuisance parameters is proposed, based on a singular value decomposition of the likelihood function, and is applied to several two-parameter models. The invariance of the approach under reparameterization is demonstrated, and the paper concludes with comments on multiparameter models.
