Subject Overview:

This subject covers linear regression methods for continuous outcome variables and logistic regression methods for binary outcome variables. The focus will be on regression methods and models used in epidemiology. The concepts of correlation (for linear regression) and proportions and odds ratios (for logistic regression) will be reviewed. Topics common to both types of regression modelling including model fitting, prediction and how to address confounding and interaction among covariates. Many simpler formula-based techniques for epidemiological analysis will be re-cast within the regression framework. Strategies for analysis including model building, model checking and regression diagnostics will be covered briefly. Extensive case studies and real-world examples will be investigated using the statistical package Stata; a key aim of this subject is to equip students with the practical skills to fit and interpret regression models.
Objectives: On completion of this subject, students are expected to:
  • Develop an understanding of the role of linear and logistic regression models in epidemiology, particularly with regard to confounding and interaction, and to relate simpler methods of epidemiological analysis to special cases of regression modelling
  • Develop practical skills in fitting and interpreting linear and logistic regression models in the statistical computing package Stata
  • Gain a practical working knowledge of model building, model checking, regression diagnostics and prediction
  • Understand essential aspects of the theory of linear and logistic regression modelling and their implications for practice.
Assessment:
  • Two written assignments equivalent to 3500 words, one on each of linear and logistic regression (the first assignment worth 30% (1,500 words) will be due mid-teaching period, the second worth 40% (2,000 words) a few weeks after the end of teaching);
  • and an end of semester examination (1.5 hours in length constituting 30% (1,500 words) of the total assessment) to be held in the University examination period.
