As part of the EHPS-Net International Summer Schools, the Radboud Summer School focused on the manipulation of longitudinal data in R Studio and learning the basics of longitudinal data analysis (logistic regression, event history analysis, and Cox models). Life course theory was used as point of departure and lectures focused on marriage, fertility and mortality. Lectures were also devoted to introduce the Historical sample of the Netherlands, and the Intermediate data Structure, as students were asked to do exercises with an IDS file. Each day, a lot of time was reserved for working with hands-on exercises and assignments. Students were guided by a series of senior teachers and local PhD-candidates to help participants work through the exercises. The students also carried out a small research project in the final days of the programme; the results of which were presented on the final day of the summer school and commented on by the three Dutch professors in historical demography (Angélique Janssens, Theo Engelen, and Jan Kok). This proved to be a very stimulating event. In total, 9 students participated from Armenia, Belgium, Hungary, Portugal, Suriname, the UK, and the Netherlands.
