  • Principal Component and Regression Analysis for Categorical Data.Application to Arterial Hypertension. 

    Navarro Céspedes, Juan M.; Casas Cardoso, Gladys M.; González Rodríguez, Emilio (2010-07-02)
    The present work is about the statistical processing of categorical data. The mathematical details of the Categorical Principal Components and the Categorical Regression Analysis are explained.The combination of both ...
  • An Alternative to Chaid Segmentation Algorithm Based on Entropy. 

    Galindo Villardón, María Purificación; Vicente Villardón, José Luis; Dorado Díaz, Ana; Vicente Galindo, María Purificación; Patino Alonso, María Carmen (2010-07-02)
    The CHAID (Chi-Squared Automatic Interaction Detection) treebased segmentation technique has been found to be an effective approach for obtaining meaningful segments that are predictive of a K-category (nominal or ordinal) ...
  • Structural Change Analysis in Linear Regression Model. 

    Pérez Salvador, Blanca Rosa; García Salazar, María Guadalupe (2010-07-02)
    Assuming that the observations are from normal distribution we obtain de distribution of the maximum likelihood ratio test if there is a change in the parameters at an unknown time and we find the maximum likehood estimators ...
  • Parameter Estimation in HIV/AIDS Epidemiological Models. 

    Barrios Ginart, Jorge; Marrero Severo, Aymée de los Ángeles; Díaz Romañach, Marta Lourdes Baguer; de Arazoza Rodríguez, Héctor (2010-07-02)
    The validation process of mathematical models that describe practical applications usually implies the estimation of the unknown parameters that are involved. In this work, in order to estimates these parameters in the ...
  • Simulated Annealing–Golden section algorithm for the multiproduct replenishment problem with stochastic demand. 

    Hernández González, Salvador; Gutiérrez Andrade, Miguel Ángel; de los Cobos Silva, Sergio Gerardo (2010-07-02)
    The joint replenishment problem (JRP) has been studied for over 30 years and there are both heuristic and exact algorithms to determine the frequency of orders and fundamental cycle; in recent years ithas been considered ...
  • Limit Theorems in Bellman–Harris Processes with Finites Second Moments 

    Llinás Solano, Humberto (2010-07-02)
    In this article are studied different theorems limits in a criticalBellman-Harris branching process with a only type of particle and with finite second moments. There were used two processes in order to figure out the ...
