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

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.

Promotores: J.C. van Houwelingen, S.A. van de Geer

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

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.

Methodology and Statistics focuses on the development, evaluation and application of statistical models for the analysis of psychological research data.

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.

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.

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

In the specialisation Methodology and Statistics, part of the Master in Psychology, you will focus on in-depth study of statistical theory and research methodology as well as on the acquisition of data analysis skills.

The programme group Research Methods and Statistics offers methodological support in many projects in the field of education and child studies.

The Graduate School of Social and Behavioural Sciences in collaboration with the Department of Methodology and Statistics and researchers in the field of Methodology and/or Statistics of the other Institutes provides training courses for PhD candidates and other researchers.

The programme group Research Methods and Statistics offers support to researchers from a variety of research projects within Education and Child Studies.

Data science is now growing fast in many places, but scholars at Leiden University have been developing data science techniques for a long time already. Thanks to their broad-based expertise, Leiden statisticians are currently combining the achievements in statistics with the latest methods of statistical…

During my PhD research, I studied the photon statistics of light emitted by a microcavity that contains a single quantum dot (QD) on resonance.

Vandaag de dag liggen statistische methodes aan de grondslag van beslissingen in allerlei facetten van het leven, van de gezondheidszorg en agricultuur tot de financiële sector en marketing.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

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

On 19 February 2019, Mirjam Sombroek-van Doorm defended her thesis 'Medisch beroepsgeheim en de zorgplicht van de arts bij kindermishandeling in de rechtsverhouding tussen arts, kind en ouders'. The doctoral research was supervised by Prof. dr. A.G. Castermans en Prof. mr. C.J.J.M. Stolker.

This dissertation is organised into three parts, each addressing a distinct research area related to Gibbs measures.

As of November 1st, Peter Grünwald has been appointed professor Statistical learning on a new chair hosted by both the Mathematical Institute and the Leiden Institute for Advanced Computer Science (LIACS).

In a recent TEDx Flanders event “Statistical Errors in Court”, Statistical Scientist Richard Gill speaks about the case of Lucia de Berk, a nurse found guilty of several murders based largely on statistics.

Overlevingsanalyse is een onderzoeksgebied dat zich richt op het bestuderen van de tijd tot het optreden van een specifieke uitkomst.

PhD defence

‘Statistics? I hated that hard subject in school’, statistician Sanne Willems is often told. And that is a pity, she thinks, because statistics doesn’t necessarily have to be difficult. Together with two former fellow students, she set up a Statistics Communication section for good communication on…
