.: 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  situations  
are also of interest in statistical theory and practice and suitable  
modifications of the original bootstrap addressing 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 samples are  discussed and some  
new results for probability proportional to size sampling are  
presented. Open issues and development challenges are also enlightened.
