Titolo:  Sampling Principles and Methods for Sensitive
and Rare Issues with relevance to Social and Environmental Studies.


Abstract:
The collection of representative  data for efficient estimation of population
characteristic is vital in all areas of statistical enquiry - none more
so than in the study of social or environmental matters.

Modern approaches to sampling which depart from the earlier principles
of randomness and segregation can yield major advantages for estimating
rare/elusive or confidential/sensitive characteristics especially when 
sample selection and testing is expensive abd optimal procedures are thus vital.

We will consider a range of methods for such matters, including:

1) weighting methods, composite sampling and randomised response methods 
for handling elusive or sensitive issues;

2) ranked set sampling for high efficiency inference where sempling costs
are vey high.
