The Introduction and Application of General Regression Model
Hrabec, Pavel ; Štarha, Pavel (referee) ; Bednář, Josef (advisor)
This thesis sumarizes in detail general linear regression model, including testing statistics for coefficients, submodels, predictions and mostly tests of outliers and large leverage points. It describes how to include categorial variables into regression model. This model was applied to describe saturation of photographs of bread, where input variables were, type of flour, type of addition and concntration of flour. After identification of outliers it was possible to create mathematical model with high coefficient of determination, which will be usefull for experts in food industry for preliminar identification of possible composition of bread.

Statistical Classification by means of generalized linear models
Sladká, Vladimíra ; Mrázková, Eva (referee) ; Michálek, Jaroslav (advisor)
The goal of this thesis is introduce the theory of generalized linear models, namely probit and logit model. This models are especially used for medical data processing. In our concrete case these mentioned models are applied to data file obtained in teaching hospital Brno. The aim is statically analyzed immune response of child patients in dependence of twelve selected types of genes and find out which combinations of these genes influence septic state of patients.

Financial Analysis of the Company HOLDES, s. r. o.
Klimo, Branislav ; Škerlíková, Tatiana (advisor) ; Marek, Petr (referee)
The bachelor thesis focuses on the financial situation of the company HOLDES, s. r. o., during the period from 2007 to 2011. The main emphasis is put on the extensive data support, particularity of specifying the methods used in the financial analysis and a detailed financial analysis itself, which aim at making the analysed field easier to understand especially for readers without any knowledge in the field of accounting or financial analysis. Company HOLDES, s. r. o., is compared to the selected competitors which are analysed along with the company during the whole analysed period. Therefore, the thesis also gives the information about the financial situation of the selected competitors and tries to stress their strengths and weaknesses. Specific contribution to the thesis represents the linear regression model whose parameter estimates allow me to distinguish the variable and fixed costs which are necessary to conduct the break-even point analysis and its use for gain management of the company. I have come to conclusion that, in comparison with the competitors, the financial indicators of the company HOLDES, s. r. o., are below the average level. On the other hand, the positive outcomes of the company from the year 2010 and the investment in the new modern machinery in the most profitable production centre from the year 2011 can ensure that the revenues in the future will be sufficient in order to reach the break-even point and make a profit.

Analýza spotřeby v ČR 1996 - 2008
Kyncl, Jan ; Tichý, Filip (advisor) ; Ráčková, Adéla (referee)
Práce se snaží vysvětlit spotřební závislosti v ČR pomocí známého tvaru makroekonomické keynesiánské spotřební funkce. V první části jsou shrnuty základní poznatky teorie lineárních regresních modelů a způsoby jejich odhadu. Dále teoretická stránka ekonomické, statistické a ekonometrické verifikace modelu. V druhé části jsou teoretické znalosti využity v praxi na reálných datech z národních účtů ČR. Je sestaven vhodný regresní model spotřeby a proveden jeho odhad a verifikace.
