Il Dipartimento di Scienze Statistiche dell'Università Cattolica del Sacro Cuore ha organizzato un seminario, presentato dal Prof. Nicola LOPERFIDO, dell'Università di Urbino "Carlo Bo", dal titolo:


Skewness-Based Projection Pursuit



Lunedì 22 Gennaio ore 11,30

in Aula G125bis



Università Cattolica del Sacro Cuore - Milano

Largo Gemelli, 1

Abstract:
Projection pursuit is a multivariate statistical technique aimed at finding interesting low-dimensional data projections. More precisely, it looks for the data projection which maximizes the projection pursuit index, that is a measure of its interestingness. Skewness, that is the third standardized cumulant, has some merits as a projection pursuit index. First, skewness is a valid projection pursuit index. Second, all distributions which are deemed uninteresting in the projection pursuit literature are symmetric. Third, for some distributions, projections maximizing skewness have a simple parametric interpretation. Finally, skewness is a mathematical concept with a simple graphical interpretation, and projection pursuit aims at making the most of visual perception as a tool for discovering data patterns. The talk will illustrate skewness-based projection pursuit from both the theoretical and the applied point of view.
