Module Overview

Regression Models I

The aim of this module is to introduce the student to multiple linear and generalised linear regression models. The statistical theory regarding these models, point and interval estimation for parameters and predicted responses is covered.  Model building techniques are critically examined. Methods for residual and influence diagnostics are introduced. The R software system (or equivalent) will be explored as a tool for fitting these models.

Motivation and formulation of the multiple regression model. Least squares (LS) and the multiple linear regression model. Variance of parameter estimates and fitted values, confidence intervals and hypothesis testing. General linear hypotheses and ANOVA.  

Model building techniques, residual and inference diagnostics and their role in model appraisal.  Including categorical predictors in regression.
