The Statistics group is responsible for research and teaching in statistics and data science.

The main methodological aspects of the use of stepwise LCA estimators under different circumstances.

The Leiden University Center for Statistical Science unites the statisticians teaching and researching at Leiden University.

The research programme Statistical Science is concerned with the analysis and interpretation of masses of data, the quantification of uncertainty using probability models, and the development and benchmarking of algorithms and methods with these aims.

The master’s programme Statistics & Data Science provides students with a thorough introduction to the general philosophy and methodology of statistical modelling and data analysis. The programme has two specialisations: Data Science and Statistical Science.

The programme group Research Methods and Statistics develops and teaches the large majority of methodological courses in all phases of the program Education and Child Studies.

This dissertation focuses on developing new mathematical and statistical methods to properly represent time-varying covariates and model them within the context of time-to-event analysis.

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

PhD candidates carry out a programme of independent research, leading to a PhD thesis in typically 4 years.

CADS researchers give methodology their own unique signature through two parallel engagements: (a) teaching and researching the full range of social science methods, from audio-visual engagements, through global ethnography, to statistical analysis; and (b) interrogating these multiple modalities employing…

How does the cluster bootstrap procedure in combination with various types of linear models perform in the analysis of longitudinal data, compared to other methods.

This thesis develops statistical methods for the analysis of high dimensional data: high dimensional networks reconstruction (Chapters 1-4), incorporation of prior information in networks reconstruction (Chapters 2-4), incorporation of prior knowledge in genetic association studies (Chapter 3).

Explaining treatment response variability between and within patients can support treatment and dosing optimization, to improve treatment of individual patients.

In 2021 the Leiden Osteoarchaeology Lab hosted an international workshop on methods to study past physical activity. It aimed to tackle a niche topic with the field: namely the method of studying muscle attachments to bone. Dr Sarah Schrader, one of the organisers of the workshop: ‘You can quantify…

In this thesis, we examine various systems through the lens of several numerical methods.
