Generalized empirical likelihood estimators and tests under partial weak and strong identification [PDF]

open access: yes, 2005
The purpose of this paper is to describe the performance of generalized empirical likelihood (GEL) methods for time series instrumental variable models specified by nonlinear moment restrictions as in Stock and Wright (2000, Econometrica 68, 1055–1096 ...

An exact corrected log-likelihood function for Cox's proportional hazards model under measurement error and some extensions [PDF]

open access: yes, 2002
This paper studies Cox`s proportional hazards model under covariate measurement error. Nakamura`s (1990) methodology of corrected log-likelihood will be applied to the so called Breslow likelihood, which is, in the absence of measurement error ...

Development of a latent dementia index in the aging, demographics, and memory study: Validation and measurement invariance by sex

open access: yesAlzheimer’s & Dementia: Diagnosis, Assessment & Disease Monitoring, 2023
Latent variable models can create a latent dementia index (LDI) using cognitive and functional ability to approximate dementia likelihood. The LDI approach has been applied across diverse cohorts.

Partial Cointegrated Vector Autoregressive Models with Structural Breaks in Deterministic Terms

open access: yesEconometrics, 2019
This paper proposes a class of partial cointegrated models allowing for structural breaks in the deterministic terms. Moving-average representations of the models are given. It is then shown that, under the assumption of martingale difference innovations,

A new tumor-associated antigen prognostic scoring system for spontaneous ruptured hepatocellular carcinoma after partial hepatectomy

open access: yesCancer Biology & Medicine, 2018
Objective: Spontaneous hepatocellular carcinoma (HCC) rupture can be fatal, and hepatic resection could achieve a favorable long-term survival among all strategies of tumor rupture.

An innovative approach to partial discharge measurement and analysis in DC insulation systems during voltage transient and in steady state

open access: yesHigh Voltage, 2021
Measuring partial discharges in DC insulation systems is an issue due to the lack of a reference relating the voltage waveform to the physics of discharge phenomena.

ANALISIS SURVIVAL DENGAN COX PROPORTIONAL HAZARD PADA KASUS DEMAM TIFOID

open access: yesMajalah Ilmiah Matematika dan Statistika, 2022
A common problem found in survival data is the presence of censored data. The length of hospitalization of Typhoid fever patients until declared cured is one of example of this data. Here, we use Cox regression model to analysis this data.
