Componentes principales y regresión logística: analizando el rendimiento académico de los estudiantes en matemática prebásica
(2011-05)
In this research we analyze the factors associated with the academic performance of students in the course of Pre-Basic Mathematics (I semester 2010-2011), from the information obtained through three questionnaires, applied ...
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 ...
Comparación de algoritmos para clustering de "streams" de series de tiempo
(2012-05)
In recent years, technological advances have resulted in a huge increment in data production as in the evolution of methods that facilitated its collection. The data that arrive continuously and massively with infinite ...
Un algoritmo para la aplicación de ingeniería reversa en sistemas biológicos
(2009-05)
Dado un conjunto de datos sobre un cuerpo finito Fq, queremos encontrar una función que interpole tales datos. Esta función se puede obtener por ingeniería reversa y es de la forma f = (f1, f2, ..., fn) : Fn −→ Fn donde ...
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 ...
Técnica de componentes indepedientes: aplicación y análisis de datos de series temporales sobre Puerto Rico
(2014-06)
The time series analysis is oriented to the problem of prediction. Perform a univariate analysis is simpler than a multivariate analysis because the univariate analysis is concerned only with the structure of internal ...
The search for experimental design with dozens of variables
(2015)
Simulation models have importantly expanded the analysis capabilities in engineering designs. With larger computing power, more variables can be modeled to estimate their effect in ever-larger number of performance measures. ...
La trasmisión de la epidemia de VIH/SIDA en Puerto Rico: modelos de regresión
(2009-05)
This research considered statistical modeling to forecast the number of deaths by AIDS in Puerto Rico using as predictors variables the number of diagnosed cases classified by transmission modes. For this study data was ...
Aplicación de componentes principales en el desarrollo de indices: social, educativo y económico para la clasificación de los municipios de Puerto Rico
(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 ...
