The purpose of the workshop is to provide an introduction to joint modelling of longitudinal and survival data and its practical relevance in health research. This three-day workshop has as main objective to give a broad introduction to various topics in the fields of longitudinal analysis, survival analysis and joint modelling. Throughout each of these topics various opportunities will be provided for participants to work with real data through modelling examples and associated computer implementation in the freely available and documented R software.
The course will be taught over three days and will cover the following topics:
Day 1: Longitudinal analysis
- Introduction to longitudinal data: examples and graphical representation
- General linear model for longitudinal data
- Parametric models for covariance structure: exploring correlation structure
- Likelihood based methods
- Marginal model
- Random effects models
- Transition models
- Diagnostics for longitudinal models
Day 2: Survival analysis
- Introduction to survival analysis: main concepts and definitions
- Descriptive approaches of survival analysis
- Regression models of survival analysis
- Introduction to survival analysis in the presence of competing risks: main concepts and definitions
- Descriptive methods for competing risks data
- Multivariable competing risks models
Day 3: Joint Modelling
- Introduction to classical joint models of time-to-event and longitudinal data
- Methodologies of joint modelling
- Extension to competing risks data
- Extensions to multivariate longitudinal outcomes and meta-analysis
- Applications of Joint Modelling in Clinical Research
- Software training session in R
