    • Algoritmo e implementación del análisis factorial de correspondencias 

      Castillo Elizondo, William; Rodríguez Rojas, Oldemar (2009-02-18)
      In this article, it is presented an algorithm in pseudo-code for the Factor Analysis of Correspondence. Some comments on the implementationn on C++ are also developed. Finally, the method is illustrated by an example.
    • Análisis de tablas múltiples con individuos cambiantes y variables fijas 

      Castillo Elizondo, William; González Varela, Jorge (2009-02-18)
      En este artículo se presenta el método Statis cuando se observan las mismas variables en todos los instantes considerados, con individuos posiblemente cambiantes. Se demuestran varias propiedades de la infraestructura y ...
    • Análisis de tablas múltiples de datos 

      Castillo Elizondo, William; González Varela, Jorge (2009-02-18)
      Two methods for analyzing multiple data tables of the French Data Analysis school are presented: the Statis method and Multiple Factor Analysis. The types of data that can be trated by each methodology area analyzed and ...
