Learning outcomes of the course unit

A student will manage both theoretical and practical knowledge of mathematical statistics and its application in the evaluation of experimental data. He will be able of testing statistical hypotheses, application of regression models and application of more advanced multivariate statistical methods in biomedicine, living environment research, analytical chemistry and and other scientific branches.
In more details:

1. Students manage the probablity theory and elementary methods of one-variate mathematical statistics on the level of point and interval estimations and tests of statistical hypotheses inbothl cases of normal and other distributions including testing of the kind of distribution.
2. Students obtain the skills in the analysis of variance - particularly in one-way and two-way ANOVA methods, Bartlett test, the methods by Tuckey and Shéffe. They make acquaintance with applications of such methods. Students will be able to verify the regularity of the application of ANOVA, or they or select another method, e.g. Kruskal-Wallis test.
3. Students manage linear regression and foundations of non-linear regression both theoratically and computationally, including interval estimations and tests of hypotheses over regression coefficients. Given a practical problem, they will be able to evaluate the adequacy of the application of the regression model.
4. Students make acquaintance with the multivariate normal distribution and the related distributions. They manage the point and interval estimations of parameters of multivariate normal distribution and tests of hypotheses on them.
5. Students manage the principal component method. They comprehend its meaning for the reduction of input parameters and its applications.
6. Students make acquaintance with the elements of the factor and discriminant analysis.
7. Students make acquaintance with the elements with the foundations of the theory of neural nets and with its possible application as an alternative to methods of classical statistics.
They manage the back-propagation alghoritm and some elementary kinds of neural nets and its applications.
