Titolo:
Understanding Bayes spaces

Abstract:
Bayes spaces contain equivalence classes of sigma-additive measures. Two 
measures are equivalent when they are proportional. These measures are 
represented by densities and vector space operations are defined. 
Probability measures and density functions are included in these spaces. 
When the densities are log-square-integrable, they are in a Hilbert 
space called B^2. Bayes spaces and associated Hilbert spaces B^2 have 
been developed in a theoretical way, but there is still a long way to 
understand the implications of the theory, as well as to develop 
potential applications. The talk is aimed at reviewing the theory and 
giving some examples of distributions for which the B^2 distance can be 
easily obtained. These examples show the variety of distribution 
supports that can be dealt with the theory. An application to grain size 
distribution is presented. The goal is to decide whether different 
populations have different mean distribution.


Tutti gli interessati sono invitati a partecipare.

Cordiali saluti,
Laura Sangalli
