The approximation of G/G/s models from Markov models M/M/s has been studied in the literature. The study of a queue model is detailed in the present article, using times of arrivals and time service distributed by Weibull whose estimation of parameters was performed with the Bayesian method...

This article discusses how the conditions of the socioeconomic environment affect mobility at the secondary, middle and upper levels of education. Our analysis focuses on the influence of parents' educational level to evaluate intergenerational mobility in education. Using a logit model of...

Determining the degree of informational asymmetry is a major topic in the literature of modern microstructure. In this paper, we review and analyze the suitability of the models for estimating the probability of informed trading [Easley et al., 1996; Nyholm, 2002, 2003]. The empirical analysis is...

It is known that, when in the linear regression model there is a high degree of multicollinearity, the results obtained by using the Ordinary Least Squares (OLS) method are unstable. As a solution to this situation, in this paper we present the raised method, the ridge method and the orthogonal...

Migration movements in the south border of México with Guatemala, has motivated serious social, economic and politic un-stability in both countries. During the last decades of the XX-th century, the sites of the south zone have become in zones with high violence indexes, delinquency and...
