[Forum SIS] Seminario Prof. Emilio Porcu

[Francesco Finazzi]

Giovedì 13 Dicembre alle ore 11.00 presso l'aula 23 del Dipartimento
di Ingegneria dell'Università di Bergamo, sede di Dalmine,

il Prof. Emilio Porcu dell'Università di Valparaíso, Valparaíso, Chile
terrà un seminario dal titolo:

"Statistical methods for massive data observed over space and time"

Abstract: statistical methods for the analysis of massive space--time
datasets are on high demand. Meteorological variables and air
pollutants are densely observed over space and time. For n sites and k
temporal instants where observations are available, the order of
computation for the likelihood is O(n^3k^3). Thus, it is necessary to
propose statistical methods that allow a considerable gain in terms of
computation whilst preserving a certain level of statistical
efficiency. In this talk, we present some classes of space--time
covariances for multivariate random fields having the important
feature of being compactly supported, that is they are identically
zero outside a finite radius. Features of such a construction are then
illustrated through real as well as artificial data analysis.

Keywords: massive datasets, space-time models, air quality assessment.


Tutti gli interessati sono cordialmente invitati a partecipare e ad
estendere l'invito a chiunque possa essere interessato.
