Goodness-of-fit tests for exponential distributions
Hlaváčová, Nikola ; Hudecová, Šárka (advisor) ; Mizera, Ivan (referee)
The thesis deals with goodness-of-fit tests for the exponential distribution. In the first part, basic concepts are introduced, including their properties. Afterwards, goodness-of- fit tests based on the empirical distribution function are presented. These tests are divided depending on whether the parameter of the distribution λ > 0 is known or unknown. If the parameter is unknown, the method of parametric bootstrap is used, where the un- known parameter λ is estimated using the maximum likelihood method. The next section presents tests utilizing some properties of the exponential distribution, such as the Gini index and Mean Residual Life. In this part, the forms of their test statistics and distribu- tions under the assumption of the null hypothesis are derived. Finally, a simulation study is presented that compares individual tests in terms of their level and power for different settings. 1

Personal Significance of Leisure Dance Activities for Non-Professional Dancers
HLAVÁČOVÁ, Nikola
The bachelor thesis deals with dancing, specifically non-professional dancing and its position in the context leisure dancing activities. The thesis consists of two parts, which are mutually connected. In the theoretical part, the work deals with dancing as a leisure activity, and the personality of a leisure educator as a dancing instructor. The thesis then focuses on factors developing the personality within the leisure dancing activity and subsequently it points to distinctive psychosocial needs typical of this team sport. In the research part, the method of qualitative research is used in the form of interviews which are then evaluated by means of the thematic data analysis. The research itself maps the experience of non-professional dancers with leisure dancing activity, and examines what subjective meaning they attach to this activity in their lives.
