In the marketing surveys and applied sociology quantitative estimates are typically based on asymptotic characteristics of sample frequencies. To overcome the problem of heterogeneity of population «quota sampling» method that reflects the main categories of the population structure is...

Because of its main characteristics like intangibility, inseparability, heterogenetiy and perishabilty, it is quite hard to understand describe and measure the service quality of municipalities. However, a number of methods for measuring service quality in the application have been developed in...

A method of small-area estimation with a utility function is developed. The utility characterises a policy planned to be implemented in each area, based on the area’s estimate of a key quantity. It is shown that the commonly applied empirical Bayes and composite estimators are inefficient for...

We provide corrections for Emura and Konno (2010). We also numerically verify the corrected formulae. Appendix gives a real data used for numerical analysis.

The list of fixed line telephone numbers, used as sampling frame for CATI surveys on households, suffers of an increasing undercoverage rate. Some methodological studies conducted on ISTAT CATI household surveys have pointed out the risk of biased estimates for particular phenomena of interest...
