چکیده
1. CASIC techniques were introduced at Istat in the 1980s. CATI and CAPI were adopted first; in a second phase, nearly one decade later, the emerging CASI techniques were taken into consideration. As for the advantages of using such new modes of operating in the data collection phase, global explicit results were obtained in terms of cost, quality and timeliness. It should be underlined that the different techniques show specific favourable characteristics that suggest how to apply them in different real situations, in order to gain the maximum advantage. For instance, it is clear that the human role of interviewers, well trained and assisted by properly designed automatic tools, can guarantee the best results in terms of quality of collected data, whereas a Web survey, when applicable, is the cheapest way of getting data from respondents. Besides, CATI/CAPI, which offer already mature and well-tested solutions, have a higher rate of consolidation than CASI techniques, which are younger and depend more on the continuously evolving IT solutions and network tools.

The concept of differential privacy has received considerable attention in the literature recently. In this paper we evaluate the masking mechanism based on Laplace noise addition to satisfy differential privacy. The results of this study indicate that the Laplace based noise addition procedure does not satisfy the requirements of differential privacy.

During recent years the imputation strategy in Statistics Finland has been concretised so that we can speak about an integrated modelling approach (IMAI) to this kind of datacleaning (see Laaksonen 2000&2002a&2003, Chambers et al 2001, Piela and Laaksonen 2001). The strategy has been under consideration and consequently further developed in the two big European Union research projects, that is,...

The European Union is facing the problem of releasing microdata in a multinational setting i.e. microdata stemming from twenty seven member states. Different laws, methodologies, practices and cultural approaches to confidentiality may severely limit the possibility of obtaining comprehensive anonymised data sets. We recall the approach adopted in Europe to design and manage harmonised statisti...

This paper describes a method for imputation in general contingency tables when the imputations are subject to both analytic (edit) constraints and probabilistic distributional constraints. The model extends edit ideas in Fellegi and Holt (1976) and Winkler and Chen (2002). The model extends missing-at-random imputation ideas in Little and Rubin (1987). Some of the ideas are related to Friedman...
