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

Small-Sample Adjustments for Wald-Type Tests Using Sandwich Estimators [PDF]
The sandwich estimator of variance may be used to create robust Wald-type tests from estimating equations that are sums of K independent or approximately independent terms. For example, for repeated measures data on K individuals, each term relates to a different individual.

Evaluation of Statistical Methods for Clustered Eye Data with Skewed Distribution [PDF]
Purpose: To evaluate the performance of various analysis approaches for skewed correlated eye data from 2 eyes of a subject in the same comparison group, which is common in ophthalmology and vision research.

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
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 ...

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
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.

A New Class of Robust Two-Sample Wald-Type Tests [PDF]
Abstract Parametric hypothesis testing associated with two independent samples arises frequently in several applications in biology, medical sciences, epidemiology, reliability and many more. In this paper, we propose robust Wald-type tests for testing such two sample problems using the minimum density power divergence estimators of the ...
