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.

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.

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.

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

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

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.

Developing and investigating statistical methods for complex data and models

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

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).

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.

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

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.

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

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

What is the best way to combine the environmental and economic data and how can we create an operational system to do so, thereby supporting the delivery of data to the Data centres on Products and Resources?

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…

Netherlands Statistics (CBS), Leiden University and the University of Amsterdam have started a collaboration in the form of a research project titled 'Enriching official economic statistics using data-driven modelling techniques'.

Novel methods for understanding key aspects that are essential to the future of Bayesian inference for high- or infinite-dimensional models and data.

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.

You may contact LUXs through any of its members or secretariats of its participating institutes. You may also reach the steering group through its chair or secretariat.

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.

The aim of this project is to determine in which cases uncertainty statements resulting from a Bayesian statistical analysis can be trusted.
