Using survey data to build contextual indicators
Seminario di Davide Morselli per i Colloquia in Social Psychology
Il 14 dicembre alle 10,30, nella Sala Seminari del Dipartimento di Scienze Politiche, Davide Morselli (Université de Lausanne) tiene il seminario "Using survey data to build contextual indicators".
Introduce Antonio Aiello.
Il seminario fa parte del ciclo Colloquia in Social Psychology, organizzato dal Dottorato in Scienze Politiche.
Abstract
Statistical techniques to investigate contextual effects, such as multilevel modeling, have become increasingly more popular in social and political science. However, context level data are not always available and sometimes need to be derived from micro data, such as responses to surveys. A common practice, for instance, is to average the survey answers given by respondents within a certain region. In this talk I will address some of the problems of this approach. In particular I will focus on measurement error, coverage error and the violation of some regression assumptions. I will also briefly present some innovative techniques that can be used to easily overcome some of these problems and allow researchers to use survey data to build contextual indicators.
