[EstudiantesMatemática]Seminario de Probabilidad y Estadística -- Viernes 13 de abril

[Andrés Sosa]

Hola

Este *viernes 13 de abril a las 10:30 horas* en el salón de seminarios del
Centro de Matemática hablará *Radu Stefan Stoica* (Université de Lorraine,
Insitut Elie Cartan de Lorraine) en el seminario de Probabilidad y
Estadística.

El título de la charla es:
*ABC Shadow algorithm: a tool for statistical analysis of spatial patterns*
Saludos.
Andrés


*Resumen:This talk presents an original ABC algorithm, {\it ABC Shadow},
that can be applied to sample posterior densities that are continuously
differentiable. The proposed algorithm solves the main condition to be
fulfilled by any ABC algorithm, in order to be useful in practice. This
condition requires enough samples in the parameter space region, induced by
the observed statistics. The algorithm is tuned on the posterior of a
Gaussian model which is entirely known, and then it is applied for the
statistical analysis of several spatial patterns. These patterns are issued
or assumed to be outcomes of point processes. The considered models are:
Strauss, Candy and area-interaction.*
