Revisiting several problems and algorithms in continuous location with lp norms
(Springer, 2014-07)
This paper addresses the general continuous single facility location problems in finite dimension spaces under possibly different ℓp norms in the demand points. We analyze the difficulty of this family of problems and ...

The generalized Weber problem with expected distances
(EDP Sciences, 1995-09)
In this paper we study a generalized Weber problem where both demand locations and the facility to be located may be regions and to be assumed to be distributed according to some probability measures inside each region. A ...

Characterizations of multinormality and corresponding tests of fit, including for Garch models
(Cornell University, 2018-05-22)
We provide novel characterizations of multivariate normality that incorporate both the characteristic function and the moment generating function, and we employ these results to construct a class of affine invariant, ...

The Power Muth Distribution
(Vilnius teach journals, 2017-03-18)
Muth introduced a probability distribution with application in reliability theory. We propose a new model from the Muth law. This paper studies its statistical properties, such as the computation of the moments, computer ...

Empirical characteristic function tests for GARCH innovation distribution using multipliers
(Taylor & Francis, 2017)
Goodness-of-fit tests for the innovation distribution in GARCH models based on measuring deviations between the empirical characteristic function of the residuals and the characteristic function under the null hypothesis ...

Solutions of optimization problems on Hadamard manifolds with Lipschitz functions
(MDPI, 2020-05-12)
The aims of this paper are twofold. First, it is shown, for the first time, which types of nonsmooth functions are characterized by all vector critical points as being efficient or weakly efficient solutions of vector ...

A Better Approach for Solving a Fuzzy Multiobjective Programming Problem by Level Sets
(MDPI, 2021-04-28)
In this paper, we deal with the resolution of a fuzzy multiobjective programming problem using the level sets optimization. We compare it to other optimization strategies studied until now and we propose an algorithm to ...

Criterio de detección de outliers en modelos probabilísticos tipo Pareto
(Instituto Nacional de Estadística, 1982)
Partiendo de una población tipo Pareto con origen de rentas H conocido, se encuentra un criterio para detección de outliers. Se estudia a continuación el caso de origen de rentas desconocido, dándose al final un criterio ...

Time series interpolation via global optimization of moments fitting
(ELSEVIER SCIENCE BV, 2013-04-16)
Most time series forecasting methods assume the series has no missing values. When missing values exist, interpolation methods, while filling in the blanks, may substantially modify the statistical pattern of the data, ...
