The Calculus of M-Estimation in R with geex [PDF]

open access: yesJournal of Statistical Software, 2020
M-estimation, or estimating equation, methods are widely applicable for point estimation and asymptotic inference. In this paper, we present an R package that can find roots and compute the empirical sandwich variance estimator for any set of user ...

A selective review of statistical methods using calibration information from similar studies

open access: yesStatistical Theory and Related Fields, 2022
In the era of big data, divide-and-conquer, parallel, and distributed inference methods have become increasingly popular. How to effectively use the calibration information from each machine in parallel computation has become a challenging task for ...

Gee-logit model corrected biplots with harvest effects on coffee beans grading

open access: yesBioscience Journal, 2021
In a granulometric analysis of coffee beans with different categories of defects, the data can be organized in contingency tables, and when considering the discrimination by harvest, they may have a structure that suggest a more complex model, by means ...

Kinetics in HBsAg after Stopping Entecavir or Tenofovir in Patients with Virological Relapse but Not Clinical Relapse

open access: yesViruses, 2022
This study investigated the kinetics in HBsAg and the HBsAg loss rate after entecavir or tenofovir disoproxil fumarate (TDF) cessation in patients with chronic hepatitis B (CHB) who achieved virological suppression after virological relapse without ...

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.

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.

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.

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 ...

An epidemiological study of the predictors of multidrug resistance and methicillin resistance among Staphylococcus spp. isolated from canine specimens submitted to a diagnostic laboratory in Tennessee, USA [PDF]

open access: yesPeerJ, 2023
Background Understanding drivers of multidrug resistance (MDR) and methicillin resistance, which have increased among canine staphylococcal isolates, is essential for guiding antimicrobial use practices.
