This book contains a selection of the papers presented at the ITACOSM 2013 Conference, held in Milan in June 2013. It is intended as an international forum of scientific discussion on the developments of theory and application of survey sampling methodologies and applications in human and natural sciences. The book gathers research papers carefully selected from both invited and contributed sessions of the conference. The whole book appears to be a relevant contribution to various key aspects of sampling methodology and techniques; it deals with some hot topics in sampling theory, such as calibration, quantile-regression and multiple frame surveys and with innovative methodologies in important topics of both sampling theory and applications. Contributions cut across current sampling methodologies such as interval estimation for complex samples, randomized responses, bootstrap, weighting, modeling, imputation, small area estimation and effective use of auxiliary information; applications cover a wide and enlarging range of subjects in official household surveys, Bayesian networks, auditing, business and economic surveys, geostatistics and agricultural statistics. The book is an updated, high level reference survey addressed to researchers, professionals and practitioners in many fields.

L'opera si propone di illustrare in modo sintetico ma sistematico le tecniche di stima dei parametri di una popolazione finita che fanno uso di informazioni ausiliarie disponibili, al fine di affrontare i problemi che emergono nelle indagini reali dove ci si trova a dover fronteggiare gli effetti delle difettosit delle basi di campionamento, della mancata osservazione di tutte le variabili da rilevare o di una parte di esse nelle unit designate a far parte del campione, degli errori di misura. Il volume si propone di rendere il lettore conscio di tali effetti e capace di farvi fronte con le tecniche che vengono descritte sottolineandone le potenzialit e i limiti al fine di una scelta consapevole.
