Robustness Property of Robust-BD Wald-Type Test for Varying-Dimensional General Linear Models [PDF]

open access: yesEntropy, 2018
An important issue for robust inference is to examine the stability of the asymptotic level and power of the test statistic in the presence of contaminated data.

Robust Statistical Inference in Generalized Linear Models Based on Minimum Renyi’s Pseudodistance Estimators

open access: yesEntropy, 2022
Minimum Renyi’s pseudodistance estimators (MRPEs) enjoy good robustness properties without a significant loss of efficiency in general statistical models, and, in particular, for linear regression models (LRMs). In this line, Castilla et al.

Statistical Inference for Odds Ratio of Two Proportions in Bilateral Correlated Data

open access: yesAxioms, 2022
Bilateral correlated data frequently arise in medical clinical studies such as otolaryngology and ophthalmology. Based on an equal correlation coefficient model, this paper mainly aimed to investigate the statistical inference for the odds ratio of two ...

Performance of model-based vs. permutation tests in the HEALing (Helping to End Addiction Long-termSM) Communities Study, a covariate-constrained cluster randomized trial

open access: yesTrials, 2022
Background The HEALing (Helping to End Addiction Long-termSM) Communities Study (HCS) is a multi-site parallel group cluster randomized wait-list comparison trial designed to evaluate the effect of the Communities That Heal (CTH) intervention compared to

Overview and evaluation of various frequentist test statistics using constrained statistical inference in the context of linear regression

open access: yesFrontiers in Psychology, 2022
Within the framework of constrained statistical inference, we can test informative hypotheses, in which, for example, regression coefficients are constrained to have a certain direction or be in a specific order. A large amount of frequentist informative

Asymptotic Sample Size for Common Test of Relative Risk Ratios in Stratified Bilateral Data

open access: yesMathematics, 2023
In medical clinical studies, various tests usually relate to the sample size. This paper proposes several methods to calculate sample sizes for a common test of relative risk ratios in stratified bilateral data.

Type I error control for cluster randomized trials under varying small sample structures

open access: yesBMC Medical Research Methodology, 2021
Background Linear mixed models (LMM) are a common approach to analyzing data from cluster randomized trials (CRTs). Inference on parameters can be performed via Wald tests or likelihood ratio tests (LRT), but both approaches may give incorrect Type I ...

Robust Test Statistics Based on Restricted Minimum Rényi’s Pseudodistance Estimators

open access: yesEntropy, 2022
The Rao’s score, Wald and likelihood ratio tests are the most common procedures for testing hypotheses in parametric models. None of the three test statistics is uniformly superior to the other two in relation with the power function, and moreover, they ...

Homogeneity Test of Many-to-One Relative Risk Ratios in Unilateral and Bilateral Data with Multiple Groups

open access: yesAxioms, 2023
In medical clinical studies, we often encounter paired organs’ unilateral or bilateral data. For bilateral data, there exists an intraclass correlation between paired organs.
