This is a course in applied statistics that studies the use of regression techniques for examining relationships between variables. Ordinary linear models and generalised linear models are covered. The course emphasizes the principles of statistical modelling through the iterative process of fitting a model, examining the fit to assess imperfections in the model and suggest alternative models, and continuing until a satisfactory model is reached. Both steps in this process require the use of a computer: model fitting uses various numerical algorithms, and model assessment involves extensive use of graphical displays. The R statistical computing package is used as an integral part of the course.
Learning Outcomes
Upon successful completion, students will have the knowledge and skills to:
Upon successful completion of this course, students will be able to:1. Demonstrate an extensive understanding of the R statistical computing language, particularly the graphical capabilities.
2. Fit simple linear regression models, interpret model parameters and relate these back to the underlying research question.
3. Analyse and interpret relatiosnhips between a response variable and a covariate.
4. Analyse and interpret relationships between a response variable and several covariates.
5. Assess and refine simple and multiple linear regression models based on diagnostic measures. Identify and discuss the implications of outlying and influential data points.
6. Select and discuss a useful multiple linear regression model from a number of competing models.
7. Define and describe the features of a Generalised Linear Model (GLM). Fit GLM models, assess and refine the models based on diagnostic measures, and interpret model output.
Indicative Assessment
Typical assessment may include, but is not restricted to: assignments and a final exam.The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.
Workload
Students are expected to commit at least 10 hours per week to completing the work in this course. This will include at least 3 contact hours per week and up to 7 hours of private study time.Requisite and Incompatibility
Preliminary Reading
There is no prescribed text, however the course draws material from:
- Faraway, Julian J. (2015) Linear Models with R, 2nd Edn, CRC/Chapman & Hall.
- Chester Ismay and Albert Y. Kim. (2017) Modern Dive: An Introduction to Statistical andData Sciences via R. http : //moderndive.com
Assumed Knowledge
The course uses the R statistical package, which uses matrix algebra to implement the regression modelling techniques. An understanding of matrix algebra (equivalent to an introductory mathematics course such as MATH1113) would be helpful in understanding how the R routines work, but such knowledge is not a required prerequisite.Fees
