Aplicación de algoritmos meméticos en la programación de horarios de clases
(2012-08)
The objective of this research is to solve a scheduling problem using memetic algorithms which solve problems with a large number of variables and constraints. This method can be applied to different scheduling problems ...

(2015-05)
Nowdays throw due to the continuous advance of technology, statisticians have been facing the need to develop new methods to extract meaningful information quickly and efficiently in large data sets, such as functional ...
Análisis del peso de los recién nacidos en Puerto Rico usando regresión a cuantiles
(2018-10-31)
This project illustrates the use of the grouped Smoothly Clipped Absolute De-
viation (SCAD), a variable selection method based on regularization, in quantile
regression to model the weight of newborns in Puerto Rico in ...
Modelo con retraso y correlación cruzada para predecir intensidad de la lluvia a corto plazo
(2012-08)
El uso de los sistemas de cómputo, permitido el mejor acondicionamiento de las predicciones que se realizan de los fenómenos atmosféricos. Sin embargo, aún este tipo de predicciones es un reto que se les presenta a la ...
Ciclos económicos de Puerto Rico: uso de modelos y técnicas estadísticas multivariadas
(2010-05)
Economic cycles provide the best monthly economic indicators of a country, both on the long and short term scale. For this reason it is necessary that the cycles model the economy to the most optimal degree possible. This ...

(2013-05)
Several findings in this research could be relevant to decision making by government agencies of Puerto Rico. This decision making depends on knowledge of the social, educational and economic aspects of the municipalities. ...
Modelos no lineales mixtos con variables de respuesta con distribución beta
(2012-06)
There are many situations in which random variables involving some kind of percentage, ratio, or fraction. Many studies have shown that linear regression models are not appropriate to model this type of data. However, the ...
Formación de coaliciones en la Corte Suprema de los Estados Unidos para las cortes naturales de los años 2006-2009 y 2010-2013 basadas en un modelo de más de una dimensión
(2013-08)
The Martin-Quinn Scores is a method developed by Andrew D. Martin and Kevin M. Quinn that predicts the ideology of the United States Supreme Court. In general, this method is a liberal/conservative scale of one dimension. ...
Rendimiento de los estudiantes del Recinto Universitario de Mayagüez en su primer curso de matemáticas : una aplicación de análisis multivariado
(2010-12)
We obtained data from 6,924 freshmen admitted to the University of Puerto Rico at Mayagüez since 2005 to 2007. For each one of these students we registered information about the following variables: Type of high school ...
The elliptic anisotropic problem with Wentzell boundary conditions and variable exponents
(2019-12-10)
Let $\Omega\subseteq\mathbb{R\!}^N$ be a bounded Lipschitz domain, for $N\geq3$. We investigate the solvability and regularity of a class of quasi-linear elliptic equations involving the anisotropic $\overset{\rightarrow ...
