This module will introduce advanced concepts and applications of linear regression models. It will start with simple linear regression with only one predictor. The difference between correlation and regression models will be revisited. For categorical predictors, linear regression models will be compared to analysis of variance with an emphasis on the generalisation of the methods as linear models. The regression assumptions and remedials will be discussed. The module will introduce multiple linear regression models with more than one predictor. The implication of multiple predictors on the interpretation of the regression results will be highlighted. The challenge of multicollinearity for continuous predictors and confounders for categorical predictors will be illustrated with real data. Regression diagnosis for outliers and influential cases will be present with suggestions on how to minimise their effects. The final part of the module will emphasise the principle of model building and variable reduction with a focus on parsimony without the loss of the research question.

Specific Topics

  •  Linear regression with one continuous predictor
  •  Linear regression with one categorical predictor
  • Regression assumptions and remedial measures
  • Regression with more than one continuous predictors
  • Regression with more than one categorical predictors
  • Interaction between two categorical predictors
  • Interaction between categorical and continuous predictors
  • Model selection and variable reduction
  • Understanding multicolinearity and remedial
  • Understanding outliers and influential cases

Prerequisite

This module requires participants to have previous knowledge of basic statistics and quantitative methods such as t-tests, simple linear regression and ANOVA. Participants will be required to demonstrate they have taken our course on Basic Stats or any other relevant quantitative course.
