Module summary

In many areas of science and social study, several variables or measurements are taken from each member of a sample. This module will examine ways of predicting one particular variable from the remaining measurements using the linear regression model. The general theory of linear regression models will be covered, including variable selection, tests and diagnostics. Robust methods will be introduced to deal with the presence of outliers.

Objectives

By the end of this module, students should be able to:
a) prove basic linear model theory using matrix algebra;
b) use a computer package to fit multiple linear regression models to data, and interpret the models;
c) apply methods of robust regression;
d) present a report on some data that the student has analyzed.

Syllabus

1. Notation.
2. Matrix Algebra. Revision of appropriate matrix theory; discussion of Cochran's theorem.
3. Multiple linear regression model. Parameter and residual estimation, introduction to the hat matrix, standard assumptions. Decomposition of sums of squares. Tests.
4. Influence. Criteria for detection and evaluation of influential cases of observations.
5. Selection of variables (forward and backward).
6. Multicollinearity - its effect on models and identification. Variance inflation factors.
7. Resistant fitting techniques for data sets with outliers. Breakdown point.
