Biología educacional: necesidad de su consideración en la formación de profesores de enseñanza media
(Universidad Católica del Maule, Facultad de Ciencias de la Educación, Escuela de Pedagogía en Lengua Castellana y Comunicación, 2015)Durante décadas se ha dejado desprovista de atención sistemática al binomio biología-educación. Esta disciplina, la Biología, ciencia indispensable de la tarea educativa, ha sido casi absolutamente ignorada en la formación ...

Birnbaum–Saunders regression models: a comparative evaluation of three approaches
(2020)This study investigates three regression models based on the Birnbaum–Saunders distribution. The first model is obtained directly through the Birnbaum–Saunders distribution; the second model is obtained via a logarithmic ...
