Abstract

EN UN PROCESO PARA ANALIZAR UNA MUESTRA DE CONSTI- TUCION DESCONOCIDA POR UN APARATO ANALITICO UN JUE GO DE MEDIDAS ANALITICAS Y UN JUEGO DE MEDIDAS DE REFERENCIA CADA UNA COMPRENDIENDO UN JUEGO DE RES- PUESTA DE SENAL MULTIVARIEDADES OBTENIDAS DE UN JU EGO DE MUESTRAS POR UN PRIMER Y UN SEGUNDO APARATO ANALITICO SON AJUSTADAS PARA REMOVER VARIAVILIDADE OPERACIONALES ASOCIADAS CON EL APARATO DANDO POR CONSIGUENTE UNA PRIMER Y UNA SEGUNDA MATRIZ DE RES PUESTAS DE SENAL AJUSTADAS UNA DE LAS DOS MATRICES DE RESPUESTAS DE SENAL AJUSTADAS ES DESCOMPUESTA A UN PRODUCTO DE MATRIZ DE UNA MATRIZ QUE COMPRENDE UN JUEGO DE FACTORES PRINCIPALES Y UNA MATRIZ QUE COMPRENDE LAS CANTIDADES ASOCIADAS CON CADA UNO DE LOS FACTORES PRINCIPALES. UN PRODUCTO DE MATRIZ DE RESPUESTA DE SENAL COMPRI MIDA ES CONSTRUIDO DE TAL MODO QUE COMPRENDE UNA MATRIZ QUE COMPRENDE UN SUBJUEGO DEL JUEGO DE FAC- TORES PRINCIPALES Y UNA MATRIZ QUE SE COMPRENDE LAS CANTIDADES ASOCIADAS CON CADA UNO DE LOS FACTO RES PRINCIPALES INCLUIDOS EN EL SUBJUEGO.DE LA UL- TIMA MATRIZ SE COMPUTA UNA MATRIZ DE PROYECCION. USANDO ESTA MATRIZ DE PROYECCION Y UN PRIMER PRODU CTO DE MATRIZ NORMALIZADO QUE COMPRENDE UNA MATRIZ DE NORMALIZACION Y LA OTRA MATRIZ DE RESPUESTA DE SENAL AJUSTADA ES CONSTRUIDO UN PRODUCTO DE MATRIZ NORMALIZADO.LOS VALORES DE LA MATRIZ DE NORMALIZA- CION QUE MINIMIZAN LA DIFERENCIA ENTRE EL PRIMER PRODUCTO DE MATRIZ NORMALIZADO Y EL PRODUCTO DE MA TRIZ NORMALIZADO COMPRIMIDO SE COMPUTAN Y POR CON- SIGUIENTE SE PRODUCE UNA MATRIZ DE NORMALIZACION OPTIMO.UN SEGUNDO PRODUCTO DE MATRIZ NORMALIZADO QUE COMPRENDE LA MATRIZ DE NORMALIZACION OPTIMO Y LA MATRIZ DE RESPUESTA DE SENAL AJUSTADAS QUE SE HABIA DESCOMPUESTO EN UN PRODUCTO DE MATRIZ ES CON STRUIDO USANDO LA OTRA MATRIZ DE RESPUESTAS DE SE- NAL AJUSTADAS Y EL SEGUNDO PRODUCTO DE MATRIZ NOR- MALIZADO UNA CALIBRACION UTIL PARA ANALIZAR LAS RE SPUESTAS DE SENAL OBTENIDAS DE LA MUESTRA DE CONS- TITUCION DESCONOCIDA POR EL PRIMER APARATO ANALITI CO ES CONSTRUIDA Y APLICADA A LAS RESPUESTAS DE SE NAL DE LA MUESTRA PARA DETERMINAR SU CONSTITUCION.
