Multiple Ordinal Correlation Based on Kendall’s Tau Measure : a Proposal
(MDPI, 2021)
The joint analysis of various ordinal variables is necessary in many experimental studies within research fields such as sociology and psychology. Therefore, the necessary measures of multiple ordinal dependence must be ...

Extended Half-Power Exponential Distribution with Applications to COVID-19 Data
(MDPI, 2022)
In this paper, the Extended Half-Power Exponential (EHPE) distribution is built on the basis of the Power Exponential model. The properties of the EHPE model are discussed: the cumulative distribution function, the hazard ...

On hub location problems in geographically flexible networks
(Wiley, 2021-04-30)
In this paper, we propose an extension of the uncapacitated hub location problem where the potential posi-tions of the hubs are not fixed in advance. Instead, they are allowed to belong to a region around an initialdiscrete ...

Flexible Log-Linear Birnbaum–Saunders Model
(MDPI, 2021-05-24)
Rieck and Nedelman (1991) introduced the sinh-normal distribution. This model was built as a transformation of a N(0,1) distribution. In this paper, a generalization based on a flexible skew normal distribution is introduced. ...

The effect of consolidated periods in heterogeneous lotsizing games
(Springer, 2022)
We consider a cooperative game defined by an economic lot-sizing problem with heterogeneous costs over a finite time horizon, in which each firm faces demand for a single product in each period and coalitions can pool ...

Spotting Key Members in Networks: Clustering-Embedded Eigenvector Centrality
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2020-11-03)
Identifying key members in a social network is critical to understand the underlying system behavior. Whereas there are several measures designed to discern the most central member, they fail to identify a central set of ...

ℓ p -type Dirichlet Spaces
(Springer, 2022-03-27)
In this paper, we consider a class of Banach spaces extending the classical Dirichlet space through the growth behaviour of the Taylor coefficients. We focus on the boundary behaviour of functions in and of the ...
