[Forum SIS] Avviso di seminario

[Anna Paganoni]

Si avvisa che in data 30-6-2011, alle ore 15:00 precise,
presso Aula Seminari F. Saleri VI Piano MOX- Dipartimento di Matematica, 
Politecnico di Milano, nell'ambito delle iniziative MOX, si svolgera' il 
seguente seminario:

Relatore: Fulvia Mecatti, University of Milano-Bicocca
Titolo: Bootstrap & Finite Population Complex Sampling

Abstract:
Since being first introduced by Efron in 1979, the Bootstrap has quickly 
become one of the most largely studied, developed and applied resampling 
method. As a consequence of its simplicity and generality there has been 
much theoretical and empirical research and the bootstrap is nowadays a 
well established computer intensive method for assessing the precision 
of an estimator, confidence intervals and p-values. In its original 
version the bootstrap applies in the classical non-parametric 
inferential context, under the customary assumption of independency and 
identical distribution (iid) of the sample observations from an unknown 
probability model. Non-iid situation are also of interest in statistical 
theory and practice and suitable modifications of the original bootstrap 
able to address a weaker or stronger dependency structure in sample data 
are needed. In the seminar first the development of bootstrap method is 
briefly reviewed and then the non-iid finite population case is focused. 
Main proposals of bootstrap algorithms for complex sample are discussed 
and some new results for probability proportional to size sampling are 
presented. Open issues and development challenges are also enlightened.


E' gradita la sua partecipazione.
Cordiali saluti.
