For the cluster randomized trial, the treatment, implemented at the cluster level, may be hypothesized to impact a final outcome of interest via a mediating variable, with the mediator and outcome being measured typically at the participant level. Two opposing views—one that allows the...

The prediction that economic freedom is beneficial in reducing corruption has not been found to be universally robust in empirical studies. The present work reviews this relationship by using firms' data in a cross-country survey and argues that approaches using aggregated macro data have not...

This paper explores variations in the uptake of breast cancer screening and associated factors influencing utilisation of mammography screening among women aged 50 to 69 years in 13 European countries. We focus on the relative importance of individual (e.g. age, education, etc.) and...

Empirical convergence analysis is typically envisaged from a macro aggregate perspective. However, researchers have recently highlighted how investigating convergence at the disaggregate level may yield interesting insights into the convergence debate. In this paper, we suggest an approach that...

As recession and financial crisis spread across Europe an increasing number of people are at risk of poverty and social exclusion. Children are more exposed to the risk of poverty and social exclusion than the overall population of the EU. The current climate of economic downturn calls out for...

This paper presents the multilevel model approach to analyzing contingent valuation surveys of individuals’ willingness to pay for reductions in the level of air pollution. It is likely that individuals living in the same area are exposed to the same level of air pollution, and accordingly...

Multilevel Analysis - Techniques and Applications is intended as an introduction to multilevel analysis for students and applied researchers, a book that can be used either in psychology, education, sociology, or business courses. Hox takes the reader step by step into the area of multilevel...

This paper presents a simultaneously study of the impact of gender and localization inequalities on the earnings of under-graduates. Using multilevel modeling, the framework draws both individual-level (i.e., pertaining to the individual elements of groups) and aggregate-level (i.e., pertaining...

In the human sciences, ability tests or psychological inventories are often repeatedly conducted to measure growth. Standard item response models do not take into account possible autocorrelation in longitudinal data. In this study, the authors propose an item response model to account for...

Formulas for estimating sample sizes are presented to provide specified levels of power for tests of significance from a longitudinal design allowing for subject attrition. These formulas are derived for a comparison of two groups in terms of single degree-of-freedom contrasts of population...
