Course contents

Time series analysis concerns the mathematical modeling of time varying phenomena, e.g., ocean waves, water levels in lakes and rivers, demand for electrical power, radar signals, muscular reactions, ECG-signals, or option prices at the stock market. The structure of the model is chosen both with regard to the physical knowledge of the process, as well as using observed data. Central problems are the properties of different models and their prediction ability, estimation of the model parameters, and the model's ability to accurately describe the data. Consideration must be given to both the need for fast calculations and to the presence of measurement errors. The course gives a comprehensive presentation of stochastic models and methods in time series analysis. Time series problems appear in many subjects and knowledge from the course is used in, e.g., automatic control, signal processing, and econometrics.

Higher education credits: 7,5 Level: A

Examination

The course examination consist of mandatory computer exercises, a take-home exam, as well as a project. As a part of the examination, a detailed project report should be handed in, as well as the result being disseminated in an oral presentation (about 10 minutes long).

Further details:

  • Computer exercises:
    • You need to sign up for the computer exercises - you can do this here. If you have not signed up for an exercise, you may only attend the session if there are available slots left; otherwise, you will be asked to leave.  
    • Exercise 0. [Do this on your own]
    • Exercise 1.
    • Exercise 2.
    • Exercise 3.
    • Please be aware that you are expected to come well prepared to the computer exercises. If you have not, you may be asked to leave.
  • Project:
    • The project is no longer available.
    • The project examination will take place on 21/12, at 13-16, in MH:309A, or on 18/1, at 13-16, in MH:309A. Choose either of these times; you cannot attend without being ready to present.
    • The project report and the presentation material should be handed in no later than at the start of the presentation. Printed versions of the project report and the take home should be handed in to the course secretary. The slides for the presentation may be mailed as a pdf to the lecturer directly.
  • Take home exam:
    • The take-home exam is no longer available. The exam is due on 21/1, at 13.15.
