STAT20230 Modern Regression Analysis

Academic Year 2022/2023

The course is intended to be a (non-exhaustive) survey of regression techniques from both a theoretical and applied perspective. Time permitting, the methods we will study include:
1. Exploratory data analysis
2. Simple Linear Regression (properties of least squares; t-test; F-test; R-squared; Confidence and Prediction Intervals)
3. Multiple Linear Regression (properties of least squares; t-test; F-test; R-squared; Confidence and Prediction Intervals)
4. Regression with Categorical Variables
5. Regression with Interaction terms
6. Polynomial Regression
7. Model Selection for Multiple Linear Models
8. Regression Diagnostics

Learning Outcomes:

By the end of the course, students should be able to:
Enter tabular data using R.
Plot data using R, to help in exploratory data analysis.
Formulate regression models for the data, while understanding some of the limitations and assumptions implicit in using these models.
Fit models using R and interpret the output.
Test for associations in a given model.
Use diagnostic plots and tests to assess the adequacy of a particular model.
Find confidence intervals for the effects of different explanatory variables in the model.
Use some basic model selection procedures, as found in R, to find a best model in a class of models.
Fit simple ANOVA models in R, treating them as special cases of multiple regression models.
