Course aims
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. This is essential for anyone contemplating a professional statistician career, or for students majoring in mathematics and statistics who are considering higher study. The components of the course (lectures, tutorials, assignments, tests and exam) will improve the research, enquiry and analytical thinking abilities of students. It will also extend their capacity and motivation for intellectual development. Essential computing skills in relation to statistical analysis of data will be developed.
Course description
This course covers multiple linear regression models and examples along with graphical methods for regression analysis. It also covers multi-variate normal distribution, quadratic forms (distributions and independence), Gauss-Markov theorem, hypothesis testing, model selection, analysis of residuals, influence diagnostics and analysis of variance.
Where content is in common with MATH2831, this course aims to give students a deeper level of understanding.
