The success of social media platforms has facilitated the emergence of various forms of online abuse within digital communities. This abuse manifests in multiple ways, including ha…
Dependent and Independent Time Series
Fredy O. Perez-Ramirez, Francisco J. Caro-Lopera, Jose A. Diaz-Garcia +1
The time series theory is set in this work under the domain of general elliptically contoured distributions. The advent of a time series approach that is in accordance with the exp…
Singular matrix variate Birnbaum-Saunders distribution under elliptical models
José A. Díaz-García, Francisco J. Caro-Lopera
This work sets the matrix variate Birnbaum-Saunders theory in the context of singular distributions and elliptical models. The so termed singular matrix variate generalised Birnbau…
Multivector variate distributions: An application in Finance
Jose. A. Diaz-Garcia, Francisco J. Caro-Lopera, Fredy O. Perez Ramirez
A new family of multivariate distributions, which shall be termed multivector variate distributions, based in the family of the multivariate contoured elliptically distribution is…
Tests about R multivariate simple linear models
Jose A. Diaz-Garcia, Oscar Alejandro Martinez-Jaime
Hypothesis about the parallelism of the regression lines in R multivariate simple linear models are studied in this paper. Tests on common intercept and sets of lines intersected a…
Matrix variate Birnbaum-Saunders distribution under elliptical models
Jose A. Diaz-Garcia, Francisco J. Caro-Lopera
This paper derives the elliptical matrix variate version of the well known univariate Birnbaum and Saunders distribution. A generalisation based on a matrix transformation is propo…
