The use of statistical methods in data mining in predicting consumer behaviour for Internet purchases
Podzimková, Michaela ; Vilikus, Ondřej (advisor) ; Berka, Petr (referee)
Data mining is a new discipline that occurs with increasing amount of stored data and the increasing need to obtain the information hidden in them. It is focused on the mining of potentially useful information from large data sets and it lies at the intersection of statistics, machine learning, artificial intelligence, databases and other areas. The aim of this thesis is to present the process of data mining with an emphasis on its connection with statistics and to describe a selection of statistical methods widely used in this field and which were also used in the applied data mining problem in this thesis. Real data from purchases in the online store show that using different methods gives different results and interesting information about purchasing behavior, and also proves that not all methods are always applicable to all types of tasks.
Population ageing in the Czech Republic and surrounding countries
Podzimková, Michaela ; Miskolczi, Martina (advisor) ; Pechholdová, Markéta (referee)
The bachelor thesis shows ageing of population over the last twenty years in the Czech Republic, Germany, Poland and the Slovak Republic using large number of demographic indicators describing the dynamics and intensity of population ageing. It aims to outline possible future developments and impacts on individuals and the society. The process of ageing has been going on for several years almost all over the world mainly due to declining natality and mortality rates and is expected to continue in the coming decades. During the reported period, there has been a large increase in the proportion of persons over fifty years and as the population ages, number of people in the oldest age groups has also rapidly increased. In the coming years, it is more likely that Old-Age Dependency Ratio will continue to increase and it will refer to a situation where the number of recipients of money from health and pension systems will be funded by a relatively small group of people in the productive age.
