Hurst Exponent and Randomness in Time Series
 Zeman, Martin ; Trešl, Jiří (advisor) ; Hušek, Roman (referee)
The main goal of this thesis is to test the ability of the Hurst exponent to recognise some processes with deterministic signal as nonrandom and to test the randomness of daily stock returns of three stocks traded in BCPP. Critical values to determine the critical region of a randomness hypothesis test were set for this purpose. Another goal of the thesis is the description of the Hurst exponent estimation by means of Rescaled Range Analysis and outline some problems accompanying this estimation if the Hurst exponent would be used as a randomness indicator. Within the frame of Rescaled Range Analysis was constructed another method that showed to be successful in recognising some series that contain deterministic signal.

Application of R/S Analysis at Financial Markets
 Vilhanová, Vanda ; Trešl, Jiří (advisor) ; Kodera, Jan (referee)
The aim of this graduation thesis is the descriptiton of R/S analysis and it's aplication on chosen time series of share prices and exchange rates. Some main models of financial time series will be mentioned in the second chapter. There will described basic linear models of stationary and non stationary time series and models of volatility. Then we will focus on the main theme of this thesis, R/S analysis. The algorithm of R/S analysis and the interpretation of the Hurst exponent will be described in the forth chapter. In the fifth chapter, the R/S analysis will by applied on real data sets. There will be two data sest of share prices of Telefónica O2 and Philip Morris and two data sets of exchange rates CZK/EUR and CZK/USD. The results will be interpreted and compared.

Fractal Market Hypothesis and R/S analysis of the Czech capital market
 Barkhanskyy, Kostyantyn ; Korbel, Jiří (advisor)
This work is aimed at the modern theory of the capital market -- Fractal Market Hypothesis. The content of my work includes both basic theoretical assumptions of the hypothesis and aplication of R/S analysis on the Czech capital market. The goal of this bachelor's thesis is to confirm Czech capital market nonlinear structure with determination it's fractal features and set the memory period by R/S analysis output.
