Course objectives
The aim of this course is to introduce the main concepts of survival analysis and basic statistical methods and models for evaluation of survival data. Students learn to understand survival data and their most common shortcomings, learn how to construct the most widely used estimates and models evaluating the impact of variables on time to the occurrence of an event of interest. The course focuses on practical applications rather than on mathematical theory and proofs.
Learning outcomes
At the end of the course, students are able:
- to understand the basic concepts of survival analysis,
- to define the survival function and the risk function and know the functional relationships between them,
- to know the basic probability distributions of survival data,
- to construct common estimates of the survival and cumulative risk functions including confidence interval,
- to define and validate the proportionality of risks,
- to apply Mantel-Haenszel logrank test for two groups,
- to describe advantages and disadvantages of nonparametric and parametric survival models,
- to formulate, explain and use proportional risk models, accelerated failure time model, Aalen's additive model and Gray's flexible model with time varying regression coefficients,
- to understand the meaning of model regression coefficients.
