Predictive models in survival analysis
Hadwigerová, Michaela ; Vítek, Martin (referee) ; Škutková, Helena (advisor)
With ever-new methods of treatment in health care occures a requierement of comparing these new methods to the old methods in some effective way. This is particularly important for the further development of these methods. However, data that describe these facts could not be processed by normal procedures and therefore was in the field of statistics to create a new kind of methods. They are known as predictive models of survival analysis.

Vlasák, Filip ; Velková, Alice (advisor) ; Klečacký, Martin (referee)
Social mobility of elites in the second half of the 19th century Abstract This thesis deals with the social mobility of senior civil servants in a very dynamic period in terms of the development of political administration in the lands of the Bohemian Crown, namely in the second half of the 19th and the beginning of the 20th century. The aim of the thesis is to analyse and describe the change in the structure of civil servants according to their social origin, to statistically determine the significant factors that influenced the age of a civil servant when he or she first took up the post of district captain and to determine whether this age was prolonged during the period under study. The analysis was conducted using data from the EXPRO 2020 research database. The results show that officials with influential social backgrounds were almost twice as likely to become district governors at a younger age than officials from lower social class backgrounds. The main results of the paper are formulated in the conclusion, which in addition to the above, discusses what effect marrying a wife from an influential background had on an official's social mobility, or how long it took an official to climb the career ladder to become a district captain after successfully graduating from university, and what factors may...

Length of doctoral studies at the Faculty of Informatics and Statistics
Hybšová, Aneta ; Malá, Ivana (advisor) ; Čabla, Adam (referee)
This thesis describes the survival analysis, exactly Kaplan-Meier estimate. A main part of the thesis deals with the problem of censored data, which is typical for survival analysis. The empirical part describes lenght of PhD studies at the Faculty of Informatics and Statistics and their "survival" in studies by Kaplan-Meier curves. First are analyzed uncensored data and then the whole data set (censored and uncensored data).
