SELT Survey Results

STAT2008/STAT6038 is a course in applied statistics that studies the use of linear regression techniques for examining relationships between variables. 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:

  1. Demonstrate a working knowledge of the R statistical computing language,particularly the graphical capabilities
  2. Fit Simple Linear regression models and interpret model parameters
  3. Summarise and analyse relationships between a response variable and a covariate
  4. Summarise and analyse relationships between a response variable and several covariates
  5. Assess and refine simple and multiple linear regression models based on diagnostic measures. Identify outlying and influential data points.
  6. Carry out model selection in a multiple linear regression modelling context.

Research-Led Teaching

My teaching in this introductory course in statistical modelling will draw on examples from my experience in statistical research and consulting.

Examination Material or equipment

You will also need access to a scientific calculator for the Final Examination.

Details of the textbook:

This textbook is a customised version created specifically for this course. It is meant to include content which is covered in the course as well as reduce the cost of purchase to students.

  • Linear Regression 1e (customised print edition) ISBN:9781307350692
  • Linear Regression 1e (ebook version). Can be bought here.

You need to have access to only 1 of these, either the print or the eBook version but not both. The books have also been requested to be added to the short-term loan of the Hancock library.

All other required materials will be provided via wattle.

Technology and Software

The application of modern statistical techniques requires familiarity with a statistical computing package. Examples provided in lectures, tutorials, and work related to the assignments will entail the use of the statistical computer packages R and RStudio, which are freely available at www.r - project.org and https : //www.rstudio.com. The program code used for examples provided in lectures and tutorials will be available on the course Wattle site. Note: students will not be able to use any statistical package during the exam.

These are some other textbooks and resources you may find very useful:


• Faraway, Julian J. (2015) Linear Models with R, 2nd Edn, CRC/Chapman & Hall.


There are multiple copies of this text on 2 hour reserve in the ANU Hancock library (Call # QA279.F37 2015) and the ANU Co-op Bookshop has copies available for purchase (cheaper e-book versions or second-hand copies of the first edition readily available, which would be fine).


For students who would like additional help getting started with R, I also recommend:


• Chester Ismay and Albert Y. Kim. (2017) Modern Dive: An Introduction to Statistical and Data Sciences via R. http : //moderndive.com

Staff Feedback

Students will be given feedback in the following forms in this course:

You will be given individual feedback by your tutor, who will mark your assignments. Solutions to the assignments will be provided on Wattle. Additionally, general verbal comments will be provided to the whole class.

You are also welcome to ask questions of me or any of the class tutors at consultations or during classes. If you wish to ask me questions immediately following a lecture, please wait for me out- side the lecture theatre, so that I can clean-up and log-off in preparation for the next class that will be using the same venue.
