Testimonials
Analysing longitudinal data is challenging… no other book compiles the relevant topics in such a pedagogical way… a must-read for both people new to longitudinal data analysis and those looking to improve their existing knowledge.
Kim Backström, PhD student, Åbo Akademi, Finland
I had a longitudinal dataset that was ideal for answering an important research question in my field, but I had no experience with longitudinal analyses. After reading this book, I felt confident enough to run the analyses myself. The paper is now ready to be submitted. I was honestly surprised that a book could help someone with zero background in longitudinal analysis do complex analyses for a real research project.
Omid Ghasemi, Postdoctoral Research Associate, University of New South Wales
Thoroughly recommend anything taught by Alex.
Michelle Degli Esposti, Postdoctoral Researcher, University of Oxford
I owe Alex’s 2018 course my ‘re-birth’ as an R data manager and analyst.
Teresio Poggio, Research Assistant, University of Trento
What I really liked about the book was how unique it was… accessible… excellent, particularly around multi-level modelling.
Emily Lowthian, Lecturer in Education, Swansea University
