Modeling public opinion over time and space: Trust in state institutions in Europe, 1989-2019

A new paper titled “Modeling Public Opinion Over Time and Space: Trust in State Institutions in Europe, 1989-2019”, co-authored by Marta Kołczyńska, Paul-Christian Bürkner, Lauren Kennedy, and Aki Vehtari, was published in Survey Research Methods. The paper estimates trends in political trust in Europe in 1989-2019 based on data from 1.7 million respondents from 13 cross-national surveys, and examines levels in political trust both overall, and by age, gender, and education.

Modeling public opinion over time: A simulation study of latent trend models

In a new paper titled “Modeling public opinion over time: A simulation study of latent trend models” and forthcoming in the Journal of Survey Statistics and Methodology, Paul Bürkner and Marta Kołczyńska propose a framework for the estimation of trends in mass public opinion based on survey data distinguishing three components: (1) the resonse model, (2) the latent trend model, and (3) representativeness adjustments. The paper focus on the second component, and compares four latent trend models that can be used for estimating trajectories of public opinion: (a) thin-plate splines, (b) Gaussian processes, (c) autoregressive models of order one, and (d) their special case, random walk models.
