Biography Danny Avello

He is studying for a PhD in the education faculty at Universidad Católica de Chile. His research is about latent variable on psychometric models.  Based on the work of Zimmerman (1975) he is using  the geometry and duality of Hilbert Spaces to improve what we can know from the observed information about the latents variable in the framework of classical test theory. His current work is on the relation between marginal distributions of the latent variable in  a population of persons and the reliability of the test from which is obtained the observed information.
