Stress-strength reliability under partially accelerated life testing using Weibull model

open access: yesScientific African, 2023
The reliability of a system is the probability that its strength exceeds its stress. This reliability is called as the stress-strength reliability. The inferences of the stress-strength reliability R=P(X>Y), when: (1) the strength (X) and stress (Y) are ...

A SAS Package for Logistic Two-Phase Studies

open access: yesJournal of Statistical Software, 2014
Two-phase designs, in which for a large study a dichotomous outcome and partial or proxy information on risk factors is available, whereas precise or complete measurements on covariates have been obtained only in a stratified sub-sample, extend the ...

Partial quasi-likelihood analysis [PDF]

open access: yesJapanese Journal of Statistics and Data Science, 2018
The quasi likelihood analysis is generalized to the partial quasi likelihood analysis. Limit theorems for the quasi likelihood estimators, especially the quasi Bayesian estimator, are derived in the situation where existence of a slow mixing component prohibits the Rosenthal type inequality from applying to the derivation of the polynomial type large ...

Empirical Likelihood for Partial Parameters in ARMA Models with Infinite Variance

open access: yesJournal of Applied Mathematics, 2014
This paper proposes a profile empirical likelihood for the partial parameters in ARMA(p,q) models with infinite variance. We introduce a smoothed empirical log-likelihood ratio statistic. Also, the paper proves a nonparametric version of Wilks’s theorem.

Pseudo-Likelihood Estimation for Parameters of Stochastic Time-Fractional Diffusion Equations

open access: yesFractal and Fractional, 2021
Although stochastic fractional partial differential equations have received increasing attention in the last decade, the parameter estimation of these equations has been seldom reported in literature.

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.
