Survival Analysis

​​Goals:

Construct parametric and non-parametric estimates of survival functions, compare two or more survival functions, estimate and interpret Cox proportional hazards model parameters

Techniques presented:

Survival Analysis Techniques (Descriptive Analysis, Survival Curves, Univariate and Multivariate Analysis)

Tutorials:

​Practical exercises are planned for each of the topics covered.

Prerequisites: 

Attending the TSC course or having knowledge of the topics it contains is preparatory. It is advisable to attend the REG course.
