IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

Social science shows a growing interest on multivariate models for discrete variables able to capture even complex pattern of relationships among a collection of observable factors. Chain Graph Models use graphs to illustrate and shape these conditional independence assumptions. Furthermore, the different types of association among variables are well represented through directed and undirected arcs. This visual tool is supported from a set of parameters that capture and describe the association. In this work we use these models to study the poverty status and particularly how this one can be affected from a group of selected variables. Several Chain Graph Models on two different cross-section data sets of Hungarian and German Household were tested. The better one for each data set is deeply studied with a particular attention to the parameters denoting the connection between the variables. From this analysis a strong effect of the considered social variables on the poverty status is highlighted in both data-sets.
