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.

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

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

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.

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 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.

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…

After the summer, the SPSS statistics programme will be replaced by the new ‘R’ software for first year students. Hemmo Smit and Sjoerd Huisman, both lecturers in Methodology and Statistics, initiated this major change in the curriculum. That did not happen overnight.

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

He is said to be one of the greatest living statisticians. Bradley Efron gave a lecture in Marekerk and opened LUXs, the Leiden University Center for Statistical Science, the first university statistics centre in the Netherlands.

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.
