Journal of Computational and Applied Mathematics, 2021 In this paper we propose a new family of estimators, Minimum Density Power Divergence Estimators (MDPDE), as a robust generalization of maximum likelihood estimators (MLE) for the loglinear model with multinomial sampling by using the Density Power Divergence (DPD) measure introduced by Basu et al. (1998).

Statistical Methods & Applications, 2020 We consider the problem of robust inference under the generalized linear model (GLM) with stochastic covariates. We derive the properties of the minimum density power divergence estimator of the parameters in GLM with random design and use this estimator to propose robust Wald-type tests for testing any general composite null hypothesis about the GLM ...

Two models for linear comparative calibration [PDF]
International Journal of Metrology and Quality Engineering, 2012 We consider the comparative calibration problem in the case when linear relationship is assumed between two considered measuring devices with possibly different units and precisions.

Robust Wald-Type Tests of One-Sided Hypotheses in the Linear Model [PDF]
Journal of the American Statistical Association, 1992 Abstract Let us consider the linear model Y = Xθ + E in the usual matrix notation, where the errors are iid. Our main objective is to develop robust Wald-type tests for a large class of hypotheses on θ; by robust we mean robustness in terms of size and power against long-tailed error distributions.

Examining DIF in the Context of CDMs When the Q-Matrix Is Misspecified
Frontiers in Psychology, 2018 The rise in popularity and use of cognitive diagnostic models (CDMs) in educational research are partly motivated by the models’ ability to provide diagnostic information regarding students’ strengths and weaknesses in a variety of content areas.
