This work, presented at the Third Chilean Congress of Forest Sciemces, was lead by Dr Nelson Ojeda. Later on, we re-designed the study, re-oriented the focus and deepness, and improved the analyses. This entirely new research was published in the journal Bosque, and was entitled Métodos estadísticos paramétricos y no-paramétricos para predecir variables de rodal basados en Landsat ETM+: una comparación en un bosque de Araucaria araucana en Chile.
