Want to learn about dynamic modeling for daily diary, experience sampling, ecological momentary assessment data? 😎

Register for our online course ‘Modeling the dynamics of intensive longitudindal data’ which starts in October 2025! 🤩

Modelling the Dynamics of Intensive Longitudinal Data (e-learning) 2025 | Utrecht Summer School
This online course covers how time series models can be used to model the dynamics of intensive longitudinal data (ILD).

I’m really excited to share that our first article has been published in the Br. J. Math. Stat. Psychol. doi.org/10.1111/bmsp...

In this paper, we evaluate and compare different non-parametric approaches for modeling non-linearity in psychological intensive longitudinal data.

Psychological concepts are increasingly understood as complex dynamic systems that change over time. To study these complex systems, researchers are increasingly gathering intensive longitudinal data...

Thank you very much and thank you for all your invaluable input, guidance, and support throughout this project.

Then I am looking forward to reading more about your analysis in the future. Do you think using a Bayesian model with priors on the number and location of the discontinuity points could be interesting for your data?

Did you by chance publish some more details on your data and analysis somewhere? I think it would be really interesting to see more on the robustness of this figure.

Thanks for the feedback, I finally got around to increase the thickness of the fitted curves. It does look better that way.

In this project, we review three non-parametric and non-linear regression techniques - local polynomial regression, Gaussian processes, and generalized additive models - within the context of intensive longitudinal data and compare how well these methods can recover psychological processes.
