Assessment criteria

High Distinction 85-100 Outstanding or exemplary performance in the following areas: interpretative ability; intellectual initiative in response to questions; mastery of the skills required by the subject, general levels of knowledge and analytic ability or clear thinking.
Distinction 75-84 Usually awarded to students whose performance goes well beyond the minimum requirements set for tasks required in assessment, and who perform well in most of the above areas.
Credit 65-74 Usually awarded to students whose performance is considered to go beyond the minimum requirements for work set for assessment. Assessable work is typically characterised by a strong performance in some of the capacities listed above.
Pass 50-64 Usually awarded to students whose performance meets the requirements set for work provided for assessment.
Fail 0-49 Usually awarded to students whose performance is not considered to meet the minimum requirements set for particular tasks. The fail grade may be a result of insufficient preparation, of inattention to assignment guidelines or lack of academic ability. A frequent cause of failure is lack of attention to subject or assignment guidelines.

Quality assurance

For the purposes of quality assurance, Bond University conducts an evaluation process to measure and document student assessment as evidence of the extent to which program and subject learning outcomes are achieved. Some examples of student work will be retained for potential research and quality auditing purposes only. Any student work used will be treated confidentially and no student grades will be affected.

Study information

Submission procedures

Students must check the [email protected] subject site for detailed assessment information and submission procedures.

Policy on late submission and extensions

A late penalty will be applied to all overdue assessment tasks unless an extension is granted by the subject coordinator. The standard penalty will be 10% of marks awarded to that assessment per day late with no assessment to be accepted seven days after the due date. Where a student is granted an extension, the penalty of 10% per day late starts from the new due date.

Policy on plagiarism

University’s Academic Integrity Policy defines plagiarism as the act of misrepresenting as one’s own original work: another’s ideas, interpretations, words, or creative works; and/or one’s own previous ideas, interpretations, words, or creative work without acknowledging that it was used previously (i.e., self-plagiarism). The University considers the act of plagiarising to be a breach of the Student Conduct Code and, therefore, subject to the Discipline Regulations which provide for a range of penalties including the reduction of marks or grades, fines and suspension from the University.

Bond University utilises Originality Reporting software to inform academic integrity.

Feedback on assessment

Feedback on assessment will be provided to students within two weeks of the assessment submission due date, as per the Assessment Policy.

Disability support

If you have a disability, illness, injury or health condition that impacts your capacity to complete studies, exams or assessment tasks, it is important you let us know your special requirements, early in the semester. Students will need to make an application for support and submit it with recent, comprehensive documentation at an appointment with a Disability Officer. Students with a disability are encouraged to contact the Disability Office at the earliest possible time, to meet staff and learn about the services available to meet your specific needs. Please note that late notification or failure to disclose your disability can be to your disadvantage as the University cannot guarantee support under such circumstances.

Additional subject information

The delivery of this subject will include the use of the R programming language, which is fully open-source. RStudio is the recommended front-end and is also freely available. A peer-evaluation system will be used in this subject to help determine the individual marks for all group assessments. As part of the requirements for Business School quality accreditation, the Bond Business School employs an evaluation process to measure and document student assessment as evidence of the extent to which program and subject learning outcomes are achieved. Some examples of student work will be retained for potential research and quality auditing purposes only. Any student work used will be treated confidentially and no student grades will be affected.

Subject curriculum

Introduction and revision of statistical modelling principles, including the importance of the bias-variance trade-off. Review of theory and application of least-squares multiple linear regression, including residual diagnostics, and re-acquaintance with the statistical software package R.

Introduces a number of variable selection methods for use in choosing an optimal subset of available independent variables. Methods are evaluated using goodness-of-fit ideas as well as cross-validated prediction errors. Both sequential and automated approaches will be covered.

Introduces model regularisation using ridge and LASSO regression. In addition, dimension reduction methods for the predictor space are considered, including principal components and partial least squares.

Introduces ordinary and weighted least-squares methods for dichotomous outcomes as well as likelihood based probit and logistic regressions. In addition, linear, quadratic and logistic discrimination are introduced along with the concepts of sensitivity, specificity, ROC curves and confusion matrices.

Examines traditional models for dealing with count responses, including Poisson and negative binomial regression models. In addition, zero-inflated and zero-truncated models are considered and applied.

Introduces models for contingency table data, including multinomial models and ordered-response models such as proportional odds and proportional hazards regressions. Model structures for testing independence are discussed, and various possible likelihood structures are introduced and explained.

Explores the traditional exponential family-based generalised linear model (GLM) structure. Applications are investigated and residual diagnostics including assessment of over-dispersion are discussed. In addition, quasi-likelihood methods for handling over-dispersion are introduced. Further, influence diagnostics are introduced as is graphical investigation of model fit and structure.

Introduces the concept of splines and smoothing models. Both B-splines and P-splines are surveyed as are local regression techniques. In addition, these spline methods are extended to introduce generalised additive model (GAM) techniques as well as multivariate adaptive regression splines (MARS).

Methods of binary search and recursive partitioning tree models are explored. In addition, modern computer-intensive statistical learning techniques which derive from trees, such as random forests are introduced and these ideas extended to the more general concepts of boosting and bootstrap aggregation (BAGGing).
