Prerequisites:

  • Enrolment into the first year of the programme.
  • Prerequisites to the written exam are the successfully completed homeworks.

Content (Syllabus outline):
Simple linear regression:

  • Assumptions, parameter estimation, statistical inference. Analysis of variance and regression. Regression through the origin.
  • Diagnostics:  analysis of residuals, analysis of special points.
  • Useful transformations.

Correlation:

  • The difference between regression and correlation model, different correlation coefficients.

Multiple regression:

  • parameter estimation, statistical inference;
  • diagnostics, multicollinearity;
  • descriptive variables in the model, model with multiple regression lines;
  • polinomial model;
  • complex linear models.
  • Nonlinear models.
  • Modelling of covariance structure (gls models).
  • Linear mixed models.
  • Objectives and competences:
    Linear models are basic statistical tool. The goals of the course are: understanding of the theory, its use in the analysis of real data, analysis of real data and interpretation of the results.

    Intended learning outcomes:
    Students acquire the knowledge for the independent work in the field of statistical modeling. This ability enables an upgrade to the different fields of scientific, research and expert work.
