Wald type and phi-divergence based test-statistics for isotonic binomial proportions [PDF]
Mathematics and Computers in Simulation, 2016 In this paper new test statistics are introduced and studied for the important problem of testing hypothesis that involves inequality constraint on proportions when the sample comes from independent binomial random variables: Wald type and phi-divergence based test-statistics.

Diagonal and unscaled Wald-type tests in general factorial designs
Electronic Journal of Statistics, 2017 In this paper, the asymptotic and permutation testing procedures are developed in general factorial designs without assuming homoscedasticity or a particular error distribution. The one-way layout, crossed and hierarchically nested designs are contained in our general framework.

Electronic Journal of Statistics, 2017 In this paper a robust version of the classical Wald test statistics for linear hypothesis in the logistic regression model is introduced and its properties are explored. We study the problem under the assumption of random covariates although some ideas with non random covariates are also considered.

Type I error control for cluster randomized trials under varying small sample structures
BMC 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
Entropy, 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 ...

Robust approach for comparing two dependent normal populations through Wald-type tests based on Rényi’s pseudodistance estimators [PDF]
Statistics and Computing, 2022 AbstractSince the two seminal papers by Fisher (Biometrika 10:507–521, 1915; Metron 1:1–32, 1921) were published, the test under a fixed value correlation coefficient null hypothesis for the bivariate normal distribution constitutes an important statistical problem.

Axioms, 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.

Generalized Wald-type tests based on minimum density power divergence estimators [PDF]
Statistics, 2015 In testing of hypothesis the robustness of the tests is an important concern. Generally, the maximum likelihood based tests are most efficient under standard regularity conditions, but they are highly non-robust even under small deviations from the assumed conditions.
