Introduction to Rates and Survival Analysis
14 - 15 May 2018
2 days (approximately 12 hours teaching).
Registration will start at 9am on the first day, the course will finish by 5pm on the final day.
The course aims to give students a grounding in the theory behind the methods most commonly used to analyse rates and survival-time data, as well as extensive hands-on experience of their application in Stata software.
Please note that 'repeated measures' analyses, in which multiple events or measurements are recorded in the same person over time, are not covered in this course. This topic is covered in the 'Analysis of Repeated Measures' course".
Students who have completed this course or who have an equivalent level of experience in survival analysis might wish to consider extending their knowledge by attending the 'Advanced Survival Analysis and Prognostic Modelling' course.
By the end of the course students should be able to:
- calculate and interpret measures of disease rates and exposure effects;
- manage and manipulate survival-time data in Stata;
- produce and interpret graphical displays appropriate for survival analysis;
- analyse survival-time data using Poisson and Cox regression models;
- discuss the uses and limitations of different methods for rates and survival analysis;
- compare and test the assumptions made by different statistical methods;
- model covariates which vary through time in survival analyses;
- interpret the results of survival analyses presented in the published literature.
Who the course is intended for
The course is intended for researchers and analysts who wish to analyse and understand data in the form of rates (events which occur over a specified period of time). We focus on popular methods of analysing these types of data, mainly Poisson and Cox regression.
Prerequisites - Participants should have a knowledge of regression analyses and their implementation in Stata of at least the level achieved in the 'Introduction to Linear and Logistic Regression Models' short course. Computer practicals are an important component of the course and will use the Stata software package. Familiarity with Stata is a pre-requisite for this course.
- Definition of rates and the relation between risks and rates.
- Manipulating person-time data in Stata using the st commands.
- Analysis of rates using Mantel-Haenszel methods and Poisson regression.
- Splitting follow up time to allow for exposures that change with time.
- Introduction to survival analysis.
- Log rank tests and Cox proportional hazards regression.
- Graphical displays for survival analysis.
- Cox models with continuously time-varying covariates.
Please note: Practical sessions of this course will be held in a computer lab, so you will not need to bring a laptop. This course will use Stata v14.0. Please bring a scientific calculator with you.
