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...

Access to information on competencies demanded by companies may be performed by a prospective study of job offers posted by employers. But, these include a large amount of quantitative and qualitative but mainly textual data, so an appropriate approach should be chosen in order to obtain a...

In this paper we introduce two general non-parametric first-order stationary time-series models for which marginal (invariant) and transition distributions are expressed as infinite-dimensional mixtures. That feature makes them the first Bayesian stationary fully non-parametric models developed...

The majority of published studies about the relation between institutional and entrepreneurial factors lack of an adequate empirical study. Due to the importance that the institutional environment has acquired in the last few years, we consider necessary a rigorous analysis using quantitative...

This paper evaluates five Nowcasting models that forecast Mexico's quarterly GDP: a Dynamic Factor Model (MFD), two Bridge Equation Models (BE) and two Principal Components Models (PCA). The results indicate that the average of the BE forecasts is statistically better than the rest of the models...

Es objeto de discusión si la política de incentivos destinada al sector minero es o no conveniente. Los partidarios defienden que gracias a esta los municipios tienen mayores oportunidades para desarrollarse, mientras que los detractores argumentan que no tiene sentido orientar recursos hacia...

La comparación de encuestas presenta problemas metodológicos recurrentes, dentro de los que destacan particularmente: i) las dificultades asociadas a la falta de continuidad, bien por el añadido de nuevas preguntas o por la eliminación de otras; ii) las dificultades propias en la selección...
