***Apologies for cross-posting*** Dear colleagues, We are excited to announce the program of the GESIS Spring Seminar 2023! The Spring Seminar offers high-quality training in state-of-the-art techniques in quantitative data analysis taught by leading experts in the field. It is designed for advanced graduate or PhD students, post-docs, as well as junior and senior researchers. In 2023, all courses will deal with techniques and methods for "Modeling Group Differences" in the social sciences and beyond. Extensive hands-on exercises and tutorials complement lectures in each course. All courses are held in English. The Spring Seminar will take place on-site in Cologne, Germany, from 27 February to 17 March 2023. Only if the pandemic hits again heavily will we move the courses online.
