Written Examination

Due: University Exam period
Weighting: 25%

This is a written exam and it is to be scheduled in the university exam period. This examination mainly involves conceptual questions or simple calculation questions. For example, it may ask students to identify an appropriate hypothesis testing method for a particular data set. For this exam, students are allowed to bring into the exam room TWO A4 paper written/typed on both sides; photocopies are not allowed. Only non-programmable calculators that do not have text retrieval capacity are allowed. Students who apply Supplementary Exams must make themselves available during supplementary exam period. 

If you receive special consideration for the final exam, a supplementary exam will be scheduled in the interval between the regular exam period and the start of the next session.  By making a special consideration application for the final exam you are declaring yourself available for a resit during the supplementary examination period and will not be eligible for a second special consideration approval based on pre-existing commitments. Please ensure you are familiar with the policy prior to submitting an application. You can check this supplementary exam information page for dates, and approved applicants will receive an individual notification one week prior to the exam with the exact date and time of their supplementary examination.

If you are given a second opportunity to sit the final examination as a result of failing to meet the minimum mark required in a hurdle assessment, you will be offered that chance during the same supplementary examination period and will be notified of the exact day and time after the publication of final results for the unit.

Supplementary exams for Session 2, 2018 will be held in the week of December 17-21, 2018.
On successful completion you will be able to:
  • Understand the fundamental difference between univariate and multivariate analysis.
  • Know how to perform hypothesis testing (mainly the Hotelling T2 test) using multivariate data.
  • Understand and be able to apply MANOVA.

Delivery and Resources

 

Classes

You are required to attend a 3-hour lecture each week; the time and room are:

Wednesday              6pm – 9pm         6 Eastern Rd (E4B),  208 Faculty PC Lab

 

Technologies used and required

We primarily use the software package R in this Unit. R is becoming increasingly important for statisticians and other scientists. More information about R can be found at the web site http://www.r-project.org/ and the package can be downloaded free of charge from there. R is very similar to the package S-PLUS and most of its codes will also work in S-Plus. From week 2, students will be given exercises each week covering materials from the lectures, and most exercises require using R.

Recommended texts

Prescribed textbook: “Applied Multivariate Statistical Analysis” by Richard A. Johnson, Dean W. Wichern (6th edition)

Students are expected to possess a copy of this textbook and are required to read certain book chapters each week. The following books may be used as other references for this unit:

DILLON & GOLDSTEIN     Multivariate Analysis – Methods and applications(QA 278 .d55)
