Flexible Birnbaum–Saunders Distribution
(MDPI, 2019-10)
In this paper, we propose a bimodal extension of the Birnbaum–Saunders model by including an extra parameter. This new model is termed flexible Birnbaum–Saunders (FBS) and includes the ordinary Birnbaum–Saunders (BS) and ...

Variable selection for Naïve Bayes classification
(Pergamon-Elsevier Science Ltd., 2021-07-06)
The Naïve Bayes has proven to be a tractable and efficient method for classification in multivariate analysis. However, features are usually correlated, a fact that violates the Naïve Bayes’ assumption of conditional ...

Revisiting a game theoretic framework for the robust railway network design against intentional attacks
(Elsevier, 2013-04-16)
This paper discusses and extends some competitive aspects of the games proposed in an earlier work, where a robust railway network design problem was proposed as a non-cooperative zero-sum game in normal form between a ...

Optimization of the Norm of a Vector-Valued DC Function and Applications
(Springer, 2000-11-01)
In this paper, we show that a DC representation can be obtained explicitly for the composition of a gauge with a DC mapping, so that the optimization of certain functions involving terms of this kind can be made by using ...

Multivariate explanatory model for sporadic carcinoma of the colon in Dukes’ stages I and IIa
(Ivyspring International Publisher, 2009)
We obtained before an explanatory model with six dependant variables: age of the patient, total cholesterol (TC), HDL cholesterol (HDL-C), VLDL cholesterol (VLDL-C), alkaline phosphatase (AP) and the CA 19.9 tumour marker. ...
