Red Door Analytics Winter School 2023

When & Where

20th – 24th November 2023

Berghs School of Communication, Bobergsgatan 48, Stockholm 11542, Sweden



Flexible parametric survival analysis, with Professor Paul Dickman

Monday 20th November

Parametric survival models are being increasingly used as an alternative to the Cox model in biomedical research. Through direct modelling of the baseline hazard function, we can gain greater understanding of the risk profile of patients over time, obtaining absolute measures of risk. Flexible parametric survival models (FPMs) incorporate restricted cubic splines on the log hazard or log cumulative hazard scale. This course will introduce the concepts, methods & software of FPMs, including extending to time-dependent effects (non-proportional hazards). We will illustrate their numerous benefits through real-world applications.


Competing risks, with Dr Caroline Dietrich

Tuesday 21st November

Competing risks models play an increasingly important role for predicting absolute risks of disease and prognosis using time to event data. An overarching goal of this course is to provide a solid introduction to important concepts in the presence of competing risks (e.g., which quantities can be estimated and what they represent) as well as practical aspects of estimation.


Multi-state models I, with Dr Michael Crowther

Wednesday 22nd November

Multi-state models allow us to model complex disease processes over time. Through the modelling of transitions between disease states, accounting for competing events at each transition, we can gain a much richer understanding of patient trajectories and how risk factors impact over the entire disease pathway. This course will introduce the concepts, methods & software of multi-state models.

Followed by a Masterclass session with guest speaker Professor Jonathan Bartlett, with Q&A hosted by Professor Paul Dickman


Multi-state models II, with Dr Michael Crowther

Thursday 23rd November 

In day 2 of multi-state models, we will focus on obtaining clinically useful and directly interpretable predictions, which are particularly useful for more complex models, but also describe the challenges and various approaches to calculating them. We will also discuss assumptions of the models, including the Markov assumption and how this can be relaxed.


Joint modelling of longitudinal and survival data, with Dr Michael Crowther

Friday 24th November

Joint models provide an effective solution to modelling a longitudinal, repeatedly measured outcome (such as blood pressure), and a survival endpoint (such as the time to death from any cause), incorporating all of the unique features that such data can entail. This course will introduce the statistical framework, underlying assumptions, estimation, model building and predictions, all motivated by clinical examples and implemented in user-friendly software.

State-of-the-art statistical models for modern HTA

At @RedDoorAnalytics, we develop methodology and software for efficient modelling of biomarkers, measured repeatedly over time, jointly with survival outcomes, which are being increasingly used in cancer settings. We have also developed methods and software for general non-Markov multi-state survival analysis, allowing for the development of more plausible natural history models, where patient history can […]

Multilevel (hierarchical) survival models: Estimation, prediction, interpretation

Hierarchical time-to-event data is common across various research domains. In the medical field, for instance, patients are often nested within hospitals and regions, while in education, students are nested within schools. In these settings, the outcome is typically measured at the individual level, with covariates recorded at any level of the hierarchy. This hierarchical structure […]

What are competing risks?

Competing risks In survival analysis, competing risks refer to the situation when an individual is at risk of experiencing an event that precludes the event under study to occur. Competing risks commonly occur in studies of cause-specific mortality, as all other causes of death than the one under study might happen before the individuals “have […]
