Outline

Overview

All models are wrong, but some are useful. Developing a useful statistical model from the available data can be challenging! For example, what should you do if a model assumption is violated, or if data are missing? Your statistical toolkit will be expanded to include modern techniques for tackling challenging issues that often exist in health research data, e.g. missing observations, non-linear effects, confounding and correlation between observations in a dataset. The methods for correlated data are relevant for analysing some epidemiological observational study designs (e.g., matched case-control studies, longitudinal studies with repeated measurements), and clinical trial designs (e.g. cluster RCTs, cross-over RCTs). Techniques to help assess the usefulness of a model will also be covered. This unit of study focuses on the application of statistical methods using the statistical software R. Topics: fractional polynomials for non-linear effects; mixed or random effects and marginal models (e.g. GEE) for correlated data; multiple imputation for missing data; propensity score for confounding; tools to assess model performance and classification.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name	Mark range	Description
High distinction	85 - 100	Demonstrates the learning outcomes at an exceptional standard
Distinction	75 - 84	Demonstrates the learning outcomes at a very high standard
Credit	65 - 74	Demonstrates the learning outcomes at a good standard
Pass	50 - 64	Demonstrates the learning outcomes at an acceptable standard
Fail	0 - 49	Does not meet the learning outcomes of the unit to a satisfactory standard

For more information see sydney.edu.au/students/guide-to-grades.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

Deduction of 5% of the maximum mark for each calendar day after the due date.
After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Learning support

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Learning outcomes

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

LO1. Develop statistical analyses in R and choose appropriate functions and packages
LO2. Fit and interpret regression models with non-linear effects
LO3. Appropriately analyse data which have missing values
LO4. Understand the principles of resampling methods and identify situations where these methods are useful
LO5. Build prediction models and assess model performance
LO6. Implement propensity score methods for confounding adjustment
LO7. Fit and interpret models for correlated data
LO8. Identify appropriate advanced statistical techniques for a given analysis task

Graduate qualities

The graduate qualities are the qualities and skills that all University of Sydney graduates must demonstrate on successful completion of an award course. As a future Sydney graduate, the set of qualities have been designed to equip you for the contemporary world.

GQ1	Depth of disciplinary expertise Deep disciplinary expertise is the ability to integrate and rigorously apply knowledge, understanding and skills of a recognised discipline defined by scholarly activity, as well as familiarity with evolving practice of the discipline.
GQ2	Critical thinking and problem solving Critical thinking and problem solving are the questioning of ideas, evidence and assumptions in order to propose and evaluate hypotheses or alternative arguments before formulating a conclusion or a solution to an identified problem.
GQ3	Oral and written communication Effective communication, in both oral and written form, is the clear exchange of meaning in a manner that is appropriate to audience and context.

Responding to student feedback

This section outlines changes made to this unit following staff and student reviews.

Lectures and tutorials will take place on seperate days of the week to allow time to complete exercises. The material covering mixed models will be covered over two weeks to accommodate public holidays. The assessments are more distributed throughout the semester to allow students to incorporate assessment feedback from one assignment to the next.
