Survival Analysis

Survival analysis is a branch of statistics for analysing the expected amount of time until some event occurs, such as death in biological organisms and failure in mechanical systems.

The course treats life length data with censoring and truncation, using models for the hazard- and survival function. Estimation of the survival function with the Nelson-Aalen and Kaplan-Meier methods is introduced, as well as methods for comparing two or more survival functions. Some parametric distributions of life lengths are defined, together with the associated parameter estimates. Non-parametric methods, the semi-parametric proportional hazard and Cox regression model, and some parametric regression models are taught as well.
