This thesis explores Breaking of Ensemble Equivalence (BEE) in random graph models by examining the spectral properties of adjacency matrices. The goal is to identify spectral characteristics that differentiate random graph ensembles, enhancing the understanding of complex network structures and beh…

The leading medical journal The Lancet has withdrawn a controversial publication on the antimalarial drug hydroxychloroquine. The reason for this is the open letter to The Lancet that over a hundred scientists signed, including Richard Gill, Leiden Professor emeritus of Mathematical statistics.

Survival Analysis for Junior Researchers 2018 was hosted in Leiden.

The aim of this project is to explore the use of statistical interaction models to quantify cross-omics and omics-drug interactions in large-scale clinical and experimental datasets

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…

This case study-based textbook in multivariate analysis for advanced students in the humanities emphasizes descriptive, exploratory analyses of various types of data sets from a wide range of sub-disciplines, promoting the use of multivariate analysis and illustrating its wide applicability. Fields…

Research of the Methodology & Statstics unit of the Institute of Psychology at Leiden University.

Statistics & Data Science is highly multidisciplinary. Within the programme we offer you a unique combination of knowledge and expertise through close collaboration.

The staff members of the Methodology & Statistics unit are members of various boards and committees.

Science is typically a patchwork of research contributions without much coordination. Especially in clinical trials, the follow-up studies that we do fail to be the most promising.

The two-year Master in Statistics & Data Science consists of 120 European Credit Transfer System (EC) points. It consists of a core set of mandatory courses, electives and a Master's Thesis Project.

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

If doctors could better estimate a patient's chances of survival, this would help in choosing a specific treatment. It would be particularly beneficial for the rare and malignant Ewing sarcoma, which mainly affects children and adolescents. Mathematics professor Marta Fiocco has been awarded a substantial…

Dementia is a progressive disease, diagnosed at a relatively late stage when intervention may not be effective. Aim of the research is to study scans of brain networks to help discover the early network changes related to dementia. Early diagnosis may benefit effectiveness of future treatment.

The research specialisation offers you the opportunity to spend two full years on training in applied mathematics to become an independent scientist with a strong theoretical basis.

Statistical considerations guide the design and implementation of the experiments that scientists perform. For instance, in a clinical trial about a the efficacy of a treatment, its effect in a certain minimum amount of patients has to be observed in order to make confident assertions about the efficacy…

The members of LUXs develop and validate new methods and algorithms for analysing data, and apply these in a wide range of problems. Their research ranges from multidisciplinary applications to proving mathematical theorems.

Social science research helps us understand human behaviour and social structures. These are determined by various factors, which makes the research complex and increases the likelihood of drawing the wrong conclusions. The choice of research method and analysis is therefore extremely important. It…

Statistical distributions in LCA and converting between different representations of these distributions.

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

We explored how to morphologically classify well-resolved jetted radio-loud active galactic nuclei (RLAGN) in the LOw Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) using machine learning.

The master's specialisation Methodology and Statistics in Psychology includes courses, a thesis and an internship. Teaching takes place in the form of seminars and small-group lectures and practicals, and is assessed primarily by written coursework and reports of empirical projects carried out individually…

The ability to collect and interpret huge quantities of data has become indispensable to society and academia. Leiden University is a knowledge and expertise centre for data science that places the emphasis on interdisciplinary collaboration and innovation.

Methodology & Statistics offers bachelor's courses and a master's specialisation.

When psychologists repeated a hundred studies in 2015, their results differed in two-thirds of the studies. ‘Research into research is not a luxury but a necessity,’ says Professor of Methodology and Statistics of Psychological Research Mark de Rooij. ‘My aim is to improve psychological research, to think…
