Students will learn how to analyse data using multiple linear regression. Multiple linear regression is a powerful statistical method for analysing a continuous outcome variable with several explanatory variables. This unit will cover how to compare more than two groups, adjust for confounders, test for effect modification, calculate adjusted means, conduct appropriate model checking, and teaches strategies for selecting the 'best' regression model. Students will learn how to apply these methods using the statistical package called SAS. The focus of this unit is on the application of fitting appropriate linear regression models and interpreting the results. The material in this unit is covered by lectures, tutorials, course notes and online discussions. This unit is the prerequiste for learning other types of regression models, such as logistic regression (PUBH5212) and survival analysis (PUBH5213).
