STAFFING:

Examiner: Peter Dunn

PRE-REQUISITES:

Pre-requisite: STA2302


RATIONALE:

A significant amount of climate research is statistically based. A climatologist should therefore have a breadth of statistical training, particularly in those methods prominent in climatological research.


SYNOPSIS:

This course extends the statistical methods learnt in previous statistics courses to include higher level methods applicable to climatology. The course introduces students to time series and forecasting and multivariate analysis, with an emphasis on the application of the methods.


OBJECTIVES:

On completion of this course students will be able to:

  • demonstrate understanding of various times series and forecasting techniques, including: fitting AR models; fitting MA models; fitting ARMA models; the ACF; the PACF; diagnostic testing; the backshift operator; Markov chains;

  • correctly apply time series and forecasting techniques to data, especially climatological data;

  • recognize which time series and forecasting techniques may be applicable in given situations;

  • demonstrate an understanding of the following multivariate analysis techniques: principal components analysis; factor analysis; cluster analysis; discriminant analysis;

  • correctly apply multivariate analysis techniques to data, especially climatological data;

  • demonstrate skill and knowledge using the R statistical software package to perform appropriate statistical analysis.

    IMPORTANT ASSESSMENT INFORMATION

    1. Attendance requirements:
      It is the students' responsibility to attend and participate appropriately in all activities (such as lectures, tutorials, laboratories and practical work) scheduled for them, and to study all material provided to them or required to be accessed by them to maximise their chance of meeting the objectives of the course and to be informed of course-related activities and administration.
    2. Requirements for students to complete each assessment item satisfactorily:
      To complete each of the assessment items satisfactorily, students must obtain at least 50% of the marks available for each assessment item.
    3. Penalties for late submission of required work:
      If students submit assignments after the due date without prior approval then a penalty of 10% of the total marks gained by the student for the assignment will apply for each working day late.
    4. Requirements for student to be awarded a passing grade in the course:
      To be assured of receiving a passing grade a student must submit all of the summative assessment items and achieve at least 50% of the available marks for those items.
    5. Method used to combine assessment results to attain final grade:
      The final grades for students will be assigned on the basis of the aggregate of the weighted marks obtained for each of the summative assessment items in the course.
    6. Examination information:
      The only materials that candidates may use in the restricted examination for this course are: writing materials (non-electronic and free from material which could give the student an unfair advantage in the examination); calculators which cannot hold textual information (students must indicate on their examination paper the make and model of any calculator(s) they use during the examination. Students whose first language is not English, may, with the Examiner's approval, take an appropriate non- electronic translation dictionary into the examination. Students who wish to use a translation dictionary MUST request and receive written approval from the Examiner at least one week before the examination date. Translation dictionaries will be subject to perusal and may be removed from the candidate's possession until appropriate disciplinary action is completed if found to contain material that could give the candidate an unfair advantage.
    7. Examination period when Deferred/Supplementary examinations will be held:
      Any Deferred or Supplementary examinations for this course will be held during the examination period at the end of the semester of the next offering of this course.
    8. University Regulations:
      Students should read USQ Regulations 5.1 Definitions, 5.6. Assessment, and 5.10 Academic Misconduct for further information and to avoid actions which might contravene University Regulations. These regulations can be found at the URL http://www.usq.edu.au/SECARIAT/calendar/Part5/ or in the printed version of the current USQ Handbook.

    ASSESSMENT NOTES

    9.Students must retain a copy of each item submitted for assessment. If requested, students will be required to provide a copy of assignments submitted for assessment purposes. Such copies should be despatched to USQ within 24 hours of receipt of a request being made.
