Possibilities of use of program R in the regression and contingency Possibilities of use of program R in the regression and contingency analysis
Ballarinová, Marie ; Blatná, Dagmar (advisor) ; Plašil, Miloslav (referee)
The aim of this bachelor thesis is to introduce the basics of the statistical program R and its application to regression and contingency analysis. The work focuses on basic user skills with data processing in the program R. The program is evaluated from many perspectives (eg, program benefits, data processing in R, working with PivotTables in R, graphs in R, import and export data, etc. .). Both analyses in this work are used for demonstration of commands and syntax for these statistics. The contribution of this work is to raise awareness about the great usefulness of the program and highlight the different functions both the analysis and the basis for statistical data processing. The main part of this work is focused on commands that can be applied directly to the command line in R in practice. The structure is divided into five main chapters. The first and second chapters provide a basic description of regression analysis and contingency. The third chapter introduces the syntax, commands and technical aspects of the program R. In the fourth and fifth chapter is application of both analyses in the program R. In the regression analysis is used simple and multiple regression analysis. The main scope of contingency analysis is working with data using tables in the program R.

The analysis confirms positive relationship between rate of aggressiveness in society (measured by homicide rate and number of housebreaking) and number of road fatalities. Others significant variables were evaluated GDP growth, tax ratio amount, unemployment rate, number of doctors, young people ratio, alcohol consumption, seat belt using and number of passenger-kilometers in country.

The econometric analysis of demand function for sugar imports to the CR in 1996-2010
Dvořáková, Lucie ; Dočkal, Dalibor (advisor) ; Řežábek, Pavel (referee)
At the turn of the 19th and 20th century, the Czech countries could boast a flourishing sugar industry. The share of the Czech countries in the European sugar exports reached to 57%. However, over time this important position on the sugar market have disappeared, and demand for imports of this commodity in the Czech Republic started to grow. The goal of this paper is to analyse the demand function for sugar import in the years 1996-2010, try to find factors that it could effect in the chosen period of time and determine their intensity. The method of examination is to set up a simple model and the subsequent implementation of regression and correlation analysis to determine the level of dependence of demand functions on individual factors. The conclusion summarizes the partial results of the analysis and proposes other possible variables that could be incorporated into the model.

Analysis of the relationship between number of bidders and procurement price for selected commodities in the Czech Republic
Radová, Lucie ; Pavel, Jan (advisor) ; Vítek, Leoš (referee)
The topic of this bachelor thesis is an examination of the effect the number of bidders and other parameters have on the cost of public procurements in the Czech Republic. File with data on 502 surplus public works, electricity supply and delivery of personal cars serves as a material for the analysis. Verification of the expected dependence is performed using multidimensional regression analysis with the help of econometric software. Through the ordinary least squares method several models are evaluated. In addition to the linear model, it is also quadratic and logarithmic models as well as a model using dummy variables for the number of bidders. The result was a finding of weak price dependence, primarily on the number of bidders and the openness of the tender.

Is the child pornography a substitute or a complement for child intercourse?
Hradečná, Anna ; Bartoň, Petr (advisor) ; Mirvald, Michal (referee)
This thesis analyzes the change in quantity demanded of sexual intercourse with minors in dependence on the cost of child pornography. Using this method it examines the type of the good, whether it is a substitute or a complement. Usage possibilities are discussed for child pornography as a complement or a substitute for child intercourse. Thereafter, regression analysis using first-differences and fixed-effects methods follows, which confirms inverse relationship between quantity demanded of sexual intercourse with minors and the cost of child pornography finding child pornography being a substitute for the demand for underage intercourse. This regression analysis is conducted based on the data from the years 2001-2008 from the USA and from the Czech Republic by using internet development as an proxy variable to measure the decline in the cost of child pornography. USA's proxy being assigned IP addresses. As an instrument IP address are used in the USA, and number of households with the internet accession Czech Republic. Estimated results served as a basis for formulating suggestions as to how to lower the number of sexual violence victims. The recommendation is reducing repression for holding child pornography.

Economic analysis of labour market disrimination
Brčák, Ondřej ; Brožová, Dagmar (advisor) ; Chytilová, Helena (referee)
The aim of this academic paper is to analyse the possible presence of discrimination against women in the job market. The analysis attempts to endogenous the discrimation section within the model. That is the essential difference in regard to other papers on this topic as these ascribe the influence of discrimination to the unexplained gender wage gap. The basic thought of this model is the idea, that if dicrimination against women is present in the job market, then it must exhibit the signs of a normal good. An examined characterisitc is the correlation of the wage gap, taken as a good, and extra variables as pensions. Investigation of possible correlation is done according to the linear regression analysis. The regression results are not satisfactory over long time periods as there are many variables that affect the outcome that the model does not consider. More precise results were achieved by means of testing individual workplaces, where especially the regression conducted with available data from analytic management occupations suggests that discrimination against women may be present
