Unit description
This unit starts with the classical normal linear regression model. The family of generalized linear models is then introduced and maximum likelihood estimators are derived. Models for counted responses, binary responses, continuous non-normal responses and categorical responses; and models for correlated responses, both normal and non-normal, and generalized additive models, are studied. All models and methods are illustrated using data sets from disciplines such as biology, actuarial studies and medicine. SAS software is used.

Assignment 1 | 15% | 20 August |
Assignment 2 | 15% | 8 October |
Assignment 3 | 15% | 29 October |
Take-home examination | 30% | 20 November |
Examination | 25% | TBA |
Due: 20 August
Weighting: 15%
Assignments should be submitted to the lecturer, by 6pm on the due date. On-campus students are expected to submit assignments at the lecture; distance students should email or mail them.
Extensions to assignments is at the discretion of the lecturer. It is the responsibility of the student to prove that there has been unavoidable disruption. Marks will be deducted for late submissions in the absence of an approved extension.
Due: 8 October
Weighting: 15%
Due: 29 October
Weighting: 15%
Due: 20 November
Weighting: 30%
You will have four days to complete the take-home examination. The timing of the take-home examination will be determined in class, once the draft University timetable has been published. (A tentative due date of 20 November has been published.)
Due: TBA
Weighting: 25%
There will be a two-hour sit-down examination. You will be permitted to bring an A4 sheet of notes, handwritten or typed, on both sides, into the sit-down examination.
Please note that students who have not performed satisfactorily in the assignments, will not be permitted to sit either the sit-down or the take-home examination. Any student who is to be excluded from the examinations, will be notified in writing of this after the due date of the last assignment.
The sit-down examination will be timetabled in the official University examination timetable. The University Examination timetable will be available in draft form approximately eight weeks before the commencement of the examinations and in final form approximately four weeks before the commencement of the examinations at: http://www.exams.mq.edu.au/exam/
The only exception to not sitting an examination at the designated time is because of documented illness or unavoidable disruption. In these circumstances you may wish to consider applying for Special Consideration. Information about unavoidable disruption and the special consideration process is available at: http://web.science.mq.edu.au/new_and_current_students/undergrad/admin_central/
A supplementary examination will only be granted if a student has satisfactory coursework. If a Supplementary Examination is granted as a result of the Special Consideration process, the examination will be scheduled after the conclusion of the official examination period.
Note that there is a University policy regarding requests for Special Consideration for examinations and the granting of supplementary examinations, which can be found at: http://www.mq.edu.au/policy/docs/special_consideration/policy.html.
You are advised that it is Macquarie University policy not to set early examinations for individuals or groups of students. All students are expected to ensure that they are available until the end of the teaching semester, that is the final day of the official examination period.

TECHNOLOGY USED
Software
We will be using the software SAS version 9.2, which is available in the computer labs in E4B. Should you need your own version of SAS, you can obtain a fully working version (with one year’s licence). Please see separate handout concerning this.
iLearn
We will be using iLearn for posting of course notes, assignments, solutions and data sets, and online discussions. You are encouraged to use the forums for discussions on the course material. Remember that if you are confused about something, the chances are that other students are also confused. Everybody benefits from the discussions, and you should not be embarrassed to admit that you do not understand a concept.
Audio recordings of lectures will be available on the iLearn site, the day after the lecture is delivered.
Course notes are available on iLearn, prior to the lecture. Students should print the notes and bring them to lectures.
Lecture: Monday 6-8pm, E4B 306
Tutorial: Monday 8-9pm, E4B 306
Students are expected to attend lectures and tutorials weekly.

Macquarie University policies and procedures are accessible from Policy Central. Students should be aware of the following policies in particular with regard to Learning and Teaching:
Academic Honesty Policy http://www.mq.edu.au/policy/docs/academic_honesty/policy.html
Assessment Policy http://www.mq.edu.au/policy/docs/assessment/policy.html
Grade Appeal Policy http://www.mq.edu.au/policy/docs/gradeappeal/policy.html
Special Consideration Policy http://www.mq.edu.au/policy/docs/special_consideration/policy.html
In addition, a number of other policies can be found in the Learning and Teaching Category of Policy Central.
Of interest to students are the policies and associated procedures on:
· Assessment

· Special consideration
· Appeal Against Final Grade Policy / Procedures / Guidelines
· Academic honesty
You should, in particular, familiarise yourself with University policy on academic honesty: http://www.mq.edu.au/policy/docs/academic_honesty/policy.html . Academic honesty is an integral part of the core values and principles contained in the Macquarie University Ethics Statement: http://www.mq.edu.au/ethics/ethic-statement-final.html. Its fundamental principle is that all staff and students act with integrity in the creation, development, application and use of ideas and information. Penalties may include a deduction of marks, failure in the unit, and/or referral to the University Discipline Committee.
Macquarie University provides a range of Academic Student Support Services. Details of these services can be accessed at: http://students.mq.edu.au/support/.
Students with a disability are encouraged to contact the Disability Support Unit who can provide appropriate help with any issues that arise during their studies.
Details of these services can be accessed at http://www.student.mq.edu.au/ses/.
If you wish to receive IT help, we would be glad to assist you at http://informatics.mq.edu.au/help/.
When using the university's IT, you must adhere to the Acceptable Use Policy. The policy applies to all who connect to the MQ network including students and it outlines what can be done.
Our graduates will take with them the intellectual development, depth and breadth of knowledge, scholarly understanding, and specific subject content in their chosen fields to make them competent and confident in their subject or profession. They will be able to demonstrate, where relevant, professional technical competence and meet professional standards. They will be able to articulate the structure of knowledge of their discipline, be able to adapt discipline-specific knowledge to novel situations, and be able to contribute from their discipline to inter-disciplinary solutions to problems.
This graduate capability is supported by:
We want our graduates to be capable of reasoning, questioning and analysing, and to integrate and synthesise learning and knowledge from a range of sources and environments; to be able to critique constraints, assumptions and limitations; to be able to think independently and systemically in relation to scholarly activity, in the workplace, and in the world. We want them to have a level of scientific and information technology literacy.
This graduate capability is supported by:
We want to develop in our students the ability to communicate and convey their views in forms effective with different audiences. We want our graduates to take with them the capability to read, listen, question, gather and evaluate information resources in a variety of formats, assess, write clearly, speak effectively, and to use visual communication and communication technologies as appropriate.
