A geometric optimally of Cox's partial likelihood
Canadian Journal of Statistics, 1999AbstractThe paper proves geometric optimality of Cox's partial likelihood score functions via estimating functions. As an illustration, Cox's proportional‐hazards model is considered.Les auteurs démontrent l'optimalité gǵométrique des fonctions scores de vraisemblance partielle de Cox au moyen des fonctions d'estimation.

Partial likelihood for online order selection
Signal Processing, 2005Partial likelihood (PL) is a flexible framework for adaptive nonlinear signal processing allowing the use of a wide class of nonlinear structures--probability models--as filters. PL maximization has been shown to be equivalent to relative entropy minimization for the general case of time-dependent observations and its large sample properties have been ...

A Partial Likelihood Estimator of Vaccine Efficacy
Australian & New Zealand Journal of Statistics, 2000A partial likelihood method is proposed for estimating vaccine efficacy for a general epidemic model. In contrast to the maximum likelihood estimator (MLE) which requires complete observation of the epidemic, the suggested method only requires information on the sequence in which individuals are infected and not the exact infection times.

Partial likelihood for real-time signal processing
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002We introduce a unified statistical framework for real-time signal processing with neural networks by using a recent extension of maximum likelihood (ML) estimation, partial likelihood (PL) estimation theory, which allows for (i) dependent observations, and (ii) processing of data using only the information that is available at the time of processing ...

Likelihood and Partial Likelihood
1988During the fifty years (1912–1962) that R.A. Fisher dominated the field of statistical research, he came out with many innovative ideas like likelihood, sufficiency, ancillarity, asymptotic efficiency, information and intrinsic accuracy, pivotal quantities and fiducial distribution, conditionality argument and recovery of ancillary information ...

A weighted partial likelihood approach for zero‐truncated models
Biometrical Journal, 2019AbstractZero‐truncated data arises in various disciplines where counts are observed but the zero count category cannot be observed during sampling. Maximum likelihood estimation can be used to model these data; however, due to its nonstandard form it cannot be easily implemented using well‐known software packages, and additional programming is often ...

Examples Questioning the Use of Partial Likelihood
The Statistician, 1987On donne des exemples qui jettent un doute sur la validite generale de l'argument de vraisemblance partielle et suggerent que des conditions plus rigoureuses soient mises en place avant une utilisation generale de la ...

Inefficiency of inferences with the partial likelihood
Communications in Statistics - Theory and Methods, 1986In two-sample semiparametric survival models other than the Cox proportional-hazards regression model, it is shown that partial-likelihood inference of structural parameters in the presence of fully nonpararnetric nuisance-hazards typically has relative efficiency zero compared with fuii-Iikelihood infer -ence.
