Abstract

La descripción se refiere a la predicción de componentes cruzados y los métodos para derivar un modelo lineal para obtener una muestra del primer componente para un bloque del primer componente a partir de una muestra del segundo componente reconstruida asociada de un bloque del segundo componente en el mismo marco, el método comprendiendo determinar los parámetros de una ecuación lineal que representa una línea recta que pasa por dos puntos, cada punto siendo definido por dos variables, la primera variable correspondiendo a un valor de muestra del segundo componente, la segunda variable correspondiendo a un valor de muestra del primer componente, con base en muestras reconstruidas tanto del primer componente como del segundo componente; y derivar el modelo lineal definido por los parámetros de línea recta.
