Tracking of health-related physical fitness in adolescent girls: a 3-year follow-up study

open access: yesBMC Pediatrics, 2022
Background Evidence has shown that higher levels of physical fitness (PF) in youth have beneficial effects on adult health-related outcomes. However, the tracking of separate PF components during adolescence has been less studied.

Restricted Empirical Likelihood Estimation for Time Series Autoregressive Models

open access: yesJournal of Statistical Theory and Applications (JSTA), 2021
In this paper, we first illustrate the restricted empirical likelihood function, as an alternative to the usual empirical likelihood. Then, we use this quasi-empirical likelihood function as a basis for Bayesian analysis of AR(r) time series models.

A Unified Theory of Confidence Regions and Testing for High-Dimensional Estimating Equations [PDF]

open access: yesStatistical Science, 2015
We propose a new inferential framework for constructing confidence regions and testing hypotheses in statistical models specified by a system of high dimensional estimating equations. We construct an influence function by projecting the fitted estimating

Developing Students’ Intuition on the Impact of Correlated Outcomes

open access: yesJournal of Statistics and Data Science Education, 2022
While correlated data methods (like random effect models and generalized estimating equations) are commonly applied in practice, students may struggle with understanding the reasons that standard regression techniques fail if applied to correlated ...

Investigation for periodic and almost periodic solutions of first-order ordinary differential equations [PDF]

open access: yesE3S Web of Conferences, 2023
Approaches to estimating for the number of periodic and almost periodic solutions of ordinary differential equations are considered. Conditions that allow determinating both the upper and lower bounds for these solutions are found.
