On the Stability of a class of Polytopes of third order square matrices and stability radiusOn the Stability of a class of Polytopes of third order square matrices and stability radius
(2011-04-29)
In this work we investigate the stability properties of a convex symmetric timeinvariant third order matrix's polytope depending on a real positive parameter $r$. We apply the obtained results to the calculation of the ...

¿Matrices policóricas / tetracóricas o matrices Pearson?: Un estudio metodológico
(Universidad San Ignacio de Loyola, 2014)
The use of product-moment correlation of Pearson is common in most studies in factor analysis in psychology, but it is known that this statistic is only applicable when the variables related are in interval scale and ...
