Nonparametric tests of independence
Kmeťková, Diana ; Pawlas, Zbyněk (advisor) ; Hlubinka, Daniel (referee)
The main objective of this thesis is the presentation regarding the problem of testing independence between two random variables in the nonparametric model of continuous cumulative distribution functions. Firstly, the reader is informed with basic notions from the theory of independence and rank tests. Afterwards, few of the most common methods for testing independence are introduced. In the beginning, the test based on Pearson's correlation coefficient is mentioned as a representative for parametric tests, then we continue with nonparametric tests, such as test based on Spearman's, Kendall's and distance correlation coefficient. We focus in better detail on Hoeffding's test of independence, which results to be consistent against all alternatives in the model of continuous cumulative distribution functions. In the end, we compare and evaluate presented methods for testing independence using simulations in R environment.

Nonparametric tests in SPSS
Kantorová, Petra ; Pecáková, Iva (advisor) ; Blatná, Dagmar (referee)
This bachelor thesis deals with description of nonparametric tests, which we can find in so called statistical packet SPSS. The first part of the thesis covers examples of this specific kind of tests (nonparametric tests), selected according to different features, its characteristics and individual steps of testing this kind of hypotheses. In the second part the reader can find me-thods of how we can use this kind of tests in SPSS. The third and last part of the bachelor thesis offers practical application and comparison of outcomes of nonparametric test.
