Universidad de Zaragoza Preservation of the log concavity by Bernstein operator with an application to ageing properties of a coherent system 2024 Access copy available to the general public Unrestricted In this paper, we provide a new proof of the preservation of the log concavity by Bernstein operator. It is based on the bivariate characterization of the likelihood ratio order. In addition, we give new conditions under which the previous property leads to preservation of ageing properties in coherent systems with independent and identically distributed components. info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 2.6 2024 MATHEMATICS, APPLIED 35 / 344 = 0.102 2024 Q1 T1 0.688 2024 Computational Mathematics 2024 Q2 Applied Mathematics 2024 Q2 4.8 2024 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Cha, J.H.
