This course introduces students to statistical model building using the important class of linear models. Topics covered in the course include how to estimate parameters in linear models, how to compare models using hypothesis testing, how to select a good model or models when prediction of the
response is the goal, and how to detect violations of model assumptions and observations which have undue influence on decisions of interest. Concepts are illustrated with applications from finance, economics, medicine, environmental science and engineering. Linear models are a fundamental component of statistical practice and the course is a solid background for more advanced statistical courses.

This course gives an understanding of the fundamentals of regression modelling, which is essential for anyone contemplating a career as a professional statistician or higher study in statistics for students majoring in mathematics and statistics. The various components of the course (lectures, tutorials, assignments, tests, exam)  will improve the research, enquiry and analytical thinking abilities of the students, as well as their capacity and motivation for intellectual development. Essential computing skills in relation to statistical analysis of data will also be developed.

Multiple linear regression models and examples. Graphical methods for regression analysis. Multi-variate normal distribution. Quadratic forms (distributions and independence), Gauss-Markov theorem. Hypothesis testing. Model selection. Analysis of residuals. Influence diagnostics. Analysis of variance.
