Abstract: I estimate the effect of being the best in the class} in the early years of schooling on future academic performance. I implement a novel methodology that does not require experimental data. My methodology exploits that some students are the best in the class because better students in the same school are assigned to…
Abstract: Este estudio trata de cómo, en el seno de la familia, se transmite el placer por la lectura. A partir de los datos de PISA 2009, la última oleada de este programa que trató en profundidad el rendimiento en comprensión lectora de los estudiantes a los 15 años, hemos mostrado que los hijos de…
Gender-based violence has become a serious issue to such an extent that it has been catalogued as a high-impact health problem by the World Health Organization. However, there is a lack of spatio-temporal analyses to reveal a complete picture of the geographical and temporal patterns of crimes against women. In this paper, we focus on…
El análisis por envoltura de datos (DEA) convencional considera el proceso productivo como una caja negra, esto es, como un proceso único que realiza la transformación de las entradas en salidas. Existen, sin embargo, enfoques DEA que abren esa caja y distinguen dentro de la misma diferentes subprocesos, cada uno con sus propias entradas y…
Presentamos un método para estimar de manera indirecta las cantidades transportadas de ciertos productos entre dos regiones en aquellos casos en los que solamente están disponibles los datos de la suma de sus flujos. Este método se basa en la aplicación de un modelo gravitacional clásico introducido en un problema de optimización. El objetivo de…
Atrial fibrillation (AF) is an abnormal rhythm of the heart that is felt as an irregular heartbeat or pulse. This disease is the most common sustained cardiac arrhythmia and increases the risk of heart failure and other heart complications. Paroxysmal AF (PAF) is defined as an intermittent AF that terminates spontaneously o with intervention in…
Abstract: The consequences that educational underperformance has on both individuals and society as a whole lead policy makers and planners to focus on how to measure it properly. The aim of this paper is to propose an index to measure educational poverty which, taking as a starting point the economic literature on multidimensional poverty measurement,…
The theory of orthogonal polynomials constitutes a nice example of the interplay between classical analysis, numerical analysis, linear algebra, probability theory and mathematical physics. In this talk we will deal with orthogonal polynomials associated with measures supported on the real line with a special emphasis on the situations where they are eigenfunctions of higher order…
El diseño experimental es la única situación en la que es significativo dentro de la teoría Bayesiana promediar sobre el espacio muestral. Como la muestra aún no se ha observado, se aplica el principio general de promediar sobre lo desconocido. Este marco justifica muchos criterios de optimalidad y abre nuevas posibilidades, por lo que varios…
A Bayesian method of moments/instrumental variable (BMOM/IV) approach is developed and applied in the analysis of the important mean and multiple regression models. Given a single set of data, it is shown how to obtain posterior and predictive moments without the use of likelihood functions, prior densities and Bayes’ Theorem. The posterior and predictive moments,…
