Graphs Subsystem in Internet Browser Environment
Vlach, Petr ; Novotný, Tomáš (referee) ; Hruška, Tomáš (advisor)
This master's thesis, divided into two sections, compares in part one existing (non-)commercial systems for OLAP presentation using contingency table or graph. The main focus is put on a graph. Results received from my observations in part one are used for implementing a graphic subsystem within internet browser's environment. User friendly interface and good arrangement of displayed data are the most important tasks.

Selected problems and methods in multivariate data analysis
Goduľová, Lenka ; Zichová, Jitka (advisor) ; Hurt, Jan (referee)
Title: Selected problems and methods in multivariate data analysis Author: Lenka Goduľová Department: Department of Probability and Mathematical Statistics Supervisor: RNDr. Jitka Zichová, Dr. Abstract: The bachelor thesis deals with processing multidimensional data. The task was to apply selected methods on financial data. The thesis is composed of the theoretical section and the analysis of a particular database. The first four chapters deal with basic relations and definitions concerning random vector and variable, multidimensional data and the independence test in a contingency table. The following section is devoted to defining the particular methods selected: cluster analysis and discriminant analysis. In the practical section these methods are applied to a database of clients of a German bank. Keywords: random vector, multivariate distribution, multivariate random variable, contingency table, cluster analysis, discriminant analysis.

Analysis of the Dependence of Population Satisfaction on Social and Economic factors
Zarembová, Petra ; Sobíšek, Lukáš (advisor) ; Blatná, Dagmar (referee)
This Bachelor thesis analyses the satisfaction of the population depending on selected social and economic factors like gender, age, health status, educational attainment level, household income, marital status and number of children. As the main goal was to describe relationship between satisfaction and several socio-economic factors of the country population. For an examination were selected four countries of the European Union, namely Germany, Poland, Spain and Sweden. The second goal was determined to find out whether a life satisfaction is different for populations of chosen countries, or if contrary they are all homogenous. Analysis of contingency tables including calculation of coefficients of dependency for nominal and ordinal variables, such as Cramer's V or Somer's d was used to carry out the analysis. The benefit of this work is a comparison of four selected European countries in terms of satisfaction of their population. Further, the statistical tests verified life satisfaction dependence on several socio-economic factors. All analysis was carried on the social and economic data, which provides online the World Survey Association free of charge.

Analysis of dependent samples in the market research
Mašková, Jana ; Pecáková, Iva (advisor) ; Coufalová, Petra (referee)
There are surveys carried out repeatedly on the same set of units. In connection with such research, we are talking about the dependent samples. The aim and the contribution of this diploma thesis is a summary of available methods for analyzing data from dependent samples for both continuous and discrete variables. The Czech literature has been devoted to this topic only marginally. The theoretical part is divided into two main parts for two waves and for more waves of exploration, which are further divided according to the type of reference variable. The third part is devoted to the application of the theoretical information in a market research.

Correspondence analysis application in MS Excel program
Ganajová, Michaela ; Řezanková, Hana (advisor) ; Pecáková, Iva (referee)
The aim of the diploma thesis was to create independently an application, automating a correspondence analysis calculation using MS Excel and taking advantage of VBA programming language. The application was then used to analyse Slovak banking sector. The created application is based on macro sets which can be split up to two parts. The first part produces a contingency table and converts it into a format usable in the second part. Then there is executed the Correspondence Analysis calculation itself. Supplement Matrix is being used, that allows to discharge functions from matrix and linear algebra. The application allows to process any matrix dimension. Dialog window offers four normalization types, shortened and also full output and it is possible to display row or column variable categories, eventually both. The analysis subject was to find out which of the products are typical for considered banks and for which clients, divided into age categories, is attractive particular bank and/or product. A starting point is a product usage data matrix at a particular bank. There was made a conclusion, that it is possible to divide banks into more traditional or modern type institutions and also that each bank has a typical product.

Correspondence analysis
Konrádová, Lucie ; Hebák, Petr (advisor) ; Plašil, Miroslav (referee)
The aim of this thesis is to introduce statistical method called Correspondence analysis as a strong instrument for exploratory data analysis. The main purpose is to understand how to interpret the correspondence map, the graphical output of this method, correctly. The method is presented both in its simple version, and its extension to multivariate data. Usage of method is demonstrated on data of non-financial subjects of Czech republic, which are entered in the register of economic subjects.
