Estudio en tiempo discreto de los procesos puntuales de incrementos condicionalmente independientes
(2009-02-18)A partir de resultados obtenidos sobre la representación binaria de los procesos puntuales en tiempo continuo, se obtiene, bajo hipótesis de separabilidad, un análogo en tiempo discreto ( procesos de incrementos casi ... -
Evaluación de un algoritmo de recocido simulado con superficies de respuestas
(2009-02-27)The solution of the geographical clustering problem includes a combinatorial classificationof the geographical units. The aggregation proposed in this work requiresan objective function that minimizes the distance between ... -
Evaluation of air pollution control policies in Mexico City using finite Markov chain observation model
(2010-04-09)This paper proposes a Markov observation based model, where the transition ma-trix is formulated using air quality monitoring data for specific pollutant emissions,with the primary objective to analyze the corresponding ... -
Experiencias con un nuevo índice de falta de ajuste en Tablas de Contingencia
(2012-04-26)Rudas, Clogg and Lindsay, en 1994, proposed a new index of lack of fit for contingency table analysis. For a contingency table P with N cells, and a model H, the new index is defined as the smallest \pi that satisfies the ... -
Fitting non-gaussian Models to Financial data: An Empirical Study
(2011-04-29)In this paper are presented some experiences about the modeling of financial data by three classes of models as alternative to Gaussian Linear models. Dynamic Volatility, Stable L'evy and Diffusion with Jumps models are ... -
Formalización de una teoría de la mentalidad
(2009-02-20)We introduce a model based in Game Theory, and those used primarily in biology(evolutionary games) to understand history. We are interested in use the model tounderstand the last years of the colony of Costa Rica. We proved ... -
Fourier coefficientes computation in two variables, a distributional version
(2015-01-01)The present article, by considering the distributional summations of Euler-Maclaurin and a suitable choice of the distribution, results in repre- sentations for the Fourier coefficients in two variables are obtained. These ... -
Fórmulas aproximadas del tipo Lévy-Khintchine
(2009-02-19)The problem of approximation of the characteristic functions defined by a PII in near intervals is studied. We establish some general properties of these functions and of the associated complex matingales, which, with the ... -
Funciones periódicas, cuasiperiódicas y clasificación de funciones
(2009-02-18)In this work we present some significative sets of functions. Following the ideas of [2] we introduce the almost periodic functions and its elementary properties. Based in [12] we give a clasification of the sets. -
Funciones regulares en el plano y operadores de Nemytskii
(2014-01-01)En este artículo mostramos que el espacio de las llamadas funciones regularizadas definidas sobre algún rectángulo del plano es un espacio de Banach. Más aún, bajo las hipótesis adecuadas damos condición necesaria ... -
Fuzzy Regression VS. Ordinary Least Squares Regression: Case Study
(2011-03-18)The objective of this paper is to disseminate the technique of fuzzy regression and to give a practical example of its use. To this end, classical regression is compared to several fuzzy regression models on a problem ... -
Generación de métricas en análisis de datos
(2009-02-20)In this work we introduce primary generators of metrics, that consist of linearcombinations of known metrics. We establish some theoretical properties of these generators,related to the computation of principal components, ... -
Generación de reglas estadísticas a partir de grandes bases de datos
(2009-02-18)Given a set of categorical variables, we want to predict one or more of them by the way rules. We propose an algorithm that (i) is guided by statistical results in a relational geometry where we use assymetrical association ... -
Generadores de números primos y factorizadores de números compuestos
(2009-02-20)The sequence of natural numbers presents itself as a multidimensional array. Twoproblems are solved on the basis of these arrays:a) distribution of prime numbers in multidimensional array,b) factoring of composite numbers.For ... -
General guidelines solution for linear programming with fuzzy coefficients
(2013-08-29)This work introduce to the Possibilistic Programming and the Fuzzy Programming as paradigms that allow to resolve problems of linear programming when the coefficients of the model or the restrictions on the same are presented ... -
Generalización a Rn de algunos métodos de interpolación conocidos en ecuaciones diferenciales
(2009-02-18)We present the Runge-Kutta methods of several one-step levels in Rn , as well as algorithms in pseudo-code for the implicit and explicit methods. We study the problem of error control in Rn and we give numerical examples ... -
