En este caso se han obtenido los estimadores de los parametros junto con su distribucion, asi como la resolucion de diversos contrastes de hipotesis sobre dichos parametros, presentando programas de ordenador que realizan tales calculos.  en todo este desarrollo se ha hecho uso de unas importantes herramientas como son el calculo diferencial matricial y el calculo de neudecicer, presentadas en el cap. 1 de la memoria.  por otra parte, en el cap. 3, se hace un estudio de tiempos de primer paso para procesos no homogeneos unidimensionales a traves de barreras variables en el tiempo, motivado por el estudio de tal cuestion sobre el proceso logaritmico-normal antes mencionado. La principal aportacion ha sido la generalizacion, para la familia de procesos no homogeneos transformados del wiemr, de los resultados conocidos para procesos homogeneos.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Aportaciones al estudio  de difusiones estocasticas no
