Analysis of Repeated Measures

This 2-day course will take place online and consist of approximately 15 hours of teaching (including a mixture of live and pre-recorded lectures and live practical sessions).

Registration will start at 9:30am on the first day and the course will finish by 4.00pm on the final day.

By the end of the course participants should be able to:

1. understand when and why repeated measures data require appropriate analysis;
2. understand and be able to use various approaches to model linear and nonlinear trajectories of continuous outcomes, with specific focus on regression splines (for nonlinear trajectories);
3. check the fit of models for continuous outcomes; and
4. have a basic understanding of other approaches for nonlinear trajectory modelling: penalised regression splines, Superimposition by Translation And Rotation (SITAR), and latent trajectory models.

This course is intended for researchers who are, or will be, involved in analysing longitudinal data.

This course will cover:

1. background: Why to collect, and how to analyse longitudinal data?;
2. an overview of mixed-effects modelling approach;
3. simple linear growth model for continuous outcomes;
4. regression spline models for nonlinear trajectories in continuous outcomes; and
5. penalised regression splines, SITAR, and latent trajectory models.

All teaching staff and tutors have extensive experience in performing analysis of repeated measures.

Participants are granted access to our virtual learning platform (Blackboard Ultra) 1 to 2 weeks in advance of the course. This allows time for any pre-course work to be completed and to familiarise with the platform.

To gain the most from the course, we recommend that you attend in full and participate in all interactive components. We endeavour to record all live lecture sessions and upload these to the online learning environment within 24 hours. This allows course participants to review these sessions at leisure and revisit them multiple times. Please note that we do not record breakout sessions.

All course participants retain access to the online learning materials and recordings for 5 months after the course. 

University of Bristol staff and postgraduate students who do not wish to attend the full course may instead register for access to the 'Materials & Recordings' version of this course: Further information and bookings.

*Attendee feedback from 2026.

Here is a sample of feedback from the last run of the course:

“Blackboard platform worked very well, all very simple. Quality of the teaching and technology was high. Particularly helpful that details, and materials, were sent in advance and given access for a while after, as I was not able to attend every session over the two days." - Course feedback, April 2026

“Enthusiastic providers, good mix of lectures and practicals. Providers are clearly very experienced in this field. Very receptive to answering questions. Use of Menti to test knowledge was helpful." - Course feedback, April 2026

“It has given me a great overview in concepts that are fairly new to me. The fact that the lectures are recorded is great as I'm definitely going to go back and watch them all again. I will be using these concepts directly in my research soon, so was also very grateful for the resources shared so I can continue my learning. Thank you." - Course feedback, April 2026

“It was a good mix of lectures and practicals with for me, the right amount of going through things together. Posit Cloud was great for me as someone who is relatively new to R. It meant that I felt a bit more supported and I think that less had potential to go wrong for me that way, e.g. not having packages installed/loaded. It particularly helped my understanding to go through the interpretation of the output in the practicals as well as in the lectures." - Course feedback, April 2026

“The course was very well structured and clear. The examples helped me understand the different approaches to analysing repeated measures data." - Course feedback, April 2026

“The course was well organised and the lectures and practicals moved seamlessly." - Course feedback, April 2026

“The lectures were very informative and well put together, and I liked the run-through of how to interpret R output as that's often where I struggle to link the theory to the application." - Course feedback, April 2026

“Very knowledgeable lecturers with good use of studies (many conducted in UoB which was nice) to illustrate application of these methods." - Course feedback, April 2026
