Emilia Rocco – författare

This book focuses on methods and models in classification and data analysis and presents real-world applications at the interface with data science. Numerous topics are covered, ranging from statistical inference and modelling to clustering and factorial methods, and from directional data analysis to time series analysis and small area estimation. The applications deal with new developments in a variety of fields, including medicine, finance, engineering, marketing, and cyber risk.The contents comprise selected and peer-reviewed contributions presented at the 13th Scientific Meeting of the Classification and Data Analysis Group of the Italian Statistical Society, CLADAG 2021, held (online) in Florence, Italy, on September 9–11, 2021. CLADAG promotes advanced methodological research in multivariate statistics with a special focus on data analysis and classification, and supports the exchange and dissemination of ideas, methodological concepts, numerical methods, algorithms, and computational and applied results at the interface between classification and data science.

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