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.

Kernel estimates of hazard function
Selingerová, Iveta ; Horová, Ivanka (advisor) ; Prášková, Zuzana (referee)
Kernel estimates of hazard function Abstract This doctoral dissertation is devoted to methods for analysis of censored data in survival analysis. The main attention is focused on the hazard function that reflects the instantaneous probability of the event occurrence within the next time instant. The thesis introduces two approaches for a kernel esti- mation of this function. In practice, the hazard function can be affected by other variables. The most frequently used model suggested by D. R. Cox is presented and moreover two types of kernel estimates to estimate a condi- tional hazard function are proposed. For kernel estimates, there is derived some statistical properties and proposed methods of bandwidths selection. The part of the thesis is extensive simulation study where theoretical results are verified and the proposed methods are compared. The last chapter of the thesis is devoted to an analysis of real data sets obtained from different fields.

Printed municipal bulletins in Prague -cast district
Černá, Michaela ; Köpplová, Barbara (advisor) ; Jüptner, Petr (referee)
Bibliografický záznam ČERNÁ, Michaela. Tištěné obecní zpravodaje v okrese Praha-východ. Praha, 2013. 220 s.: Rigorózní práce (Mgr.) Univerzita Karlova, Fakulta sociálních věd, Institut komunikačních studií a žurnalistiky. Katedra mediálních studií. Vedoucí rigorózní práce Doc. PhDr. Barbara Köpplová, CSc. ABSTRACT Municipal bulletins are specific type of local media, which are not described enough in the Czech Republic. Theses Printed Municipal Bulletins in Prague-East District (Theses) should extend the work, which is necessary for an objective understanding of the functioning of this part of media landscape. The content of Theses is the description of municipal bulletins in the selected region. In the first part, Theses summarizes the theoretical knowledge about municipal bulletins. It presents the basic terminology, legal aspects of municipal bulletins, functions of local media including municipal bulletins and ethical aspects of their publishing. Furthermore, Theses briefly defines researched region and describes methodology, which is used in the practical part of Theses. The practical part of Theses examines municipal bulletins in the Prague-East district. It brings together the list of them and analyzes some of them in detail. On this selected sample of municipal bulletins of Prague-East district...

Analysis of the Survival and its Application in Risk Management
Kawuloková, Zuzana ; Komárková, Lenka (advisor) ; Magyar, Tomáš (referee)
The main objective of this thesis is to describe methodological approaches used in survival analysis and investigate the possibility of its uses in processes of credit risk modeling in bank. The thesis focuses at Kaplan-Meier and Life-table estimations of survival function, Kaplan-Meier estimation of hazard function and function of cumulative hazard and so called log-rank test. Estimations are performed on real bank data and obtained results are discussed in term of credit risk modeling. In the thesis is demonstrated that survival analysis can be strong instrument on the field of credit risk support analyses even though it is still recommended to use it in combination with other approaches.
