Objectives
After passing this course the student understands what robustness means and knows which tools can be used for studying robustness of estimators (filters). Student will also be familiar with several robust estimators.

Content
Content Core content Complementary knowledge Specialist knowledge
1. The meaning of robustness, deviations from parametric models and estimation theory.  Chebychev¿s inequality, information inequality, unbiasedness, consistency, efficiency and basics of detection.  Minimax approach. 
2. Influence function (IF), gross-error sensitivity, local-shift sensitivity, rejection point, asymptotic variance, breakdown point.  Finite-sample versions of the IF and output distributional influence function (ODIF).    
3. Order Statistics (OS) and stack filters and their distributions.  Optimization of the stack filters.    
4. Definitions of M-, L-, and R-estimators.  Spefific properties of these different estimator classes. Redescending M-estimators and matched median filter.    

Requirements for completing the course
One seminar presentation and final exam.

    Remarks

    From the book by Hampel et al. the first two chapters are studied on this course.

  • Partial passing of course must be in connection with the same round of implementation.

  • The course is suitable for postgraduate studies.

  • Distance learning

  • ITC utilized during the course

  • - In information distribution via homepage, newsgroups or mailing lists, e.g. current issues, timetables
    - In compiling teaching material, particularly for online use or other electronic media
    - In distributing and/or returning exercise work, material etc

  • Estimate as a percentage of the implementation of the course
  • - Contact teaching: 50 %
    - Distance learning: 0 %
    - Proportion of a student's independent study: 50 %
