Dear colleagues,

When are group differences genuine, and when are they shaped by methodological artifacts or compositional imbalances? GESIS invites you to explore these and other questions in our upcoming workshops on modeling group differences. Topics range from ensuring measurement comparability across groups to accounting for nested data structures: * 27. - 30.01. Decomposition Methods in the Social Scienceshttps://tinyurl.com/01-25-decomposition-methods (Mannheim) * 18. - 19.02. Propensity Score Matching: Computation and Balance Estimation for two and more groups in Rhttps://tinyurl.com/02-25-PSM-comp-balance-R (Online) * 3. 12. - 14.03. Einführung in Strukturgleichungsmodellierunghttps://tinyurl.com/03-25-struktgleichungsmodel (Online) * 14. - 16.04.
