Abstract: The Kendall rank correlation coefficient, based on the Kendall-τ� distance, is used to measure the ordinal association between two measurements. In this paper, we introduce a new coefficient also based on the Kendall-τ� distance, the Concordance coefficient, and a test to measure whether […]

Faltys, O., Hobza, T., Morales, D. (2022) "Small area estimation under area-level generalized linear mixed models", Communications in Statistics: Simulation and Computation, 51 (12):7404–7426
Ondřej Faltys, Tomáš Hobza (Czech Technical University in Prague) and Domingo Morales (Operations Research Center, University Miguel Hernández of Elche)
Abstract:This paper introduces a general area-level model-based formulation to small area estimation based on generalized linear mixed models. By applying an optimization algorithm to the Laplace approximation of the likelihood, the maximum likelihood estimators of the model […]
