Analysis of Selected Climatological Time Series
Kraitz, Petr ; Helman, Karel (advisor) ; Šimpach, Ondřej (referee)
Dissertation is focused on analysis of time series of monthly mean temperatures of seven meteorological stations between years 1960 to 2015. With the use of selected statistical methods time series are modelled in moving ten year long intervals and a forecast of elevenths year is constructed. The goal of this dissertation is to compare the success of different methods/models predictions of values for one year period, based on the data from last 10 years.

Analysis of monthly time series of temperatures at chosen stations in Europe
Henkrichová, Jana ; Helman, Karel (advisor) ; Řezanková, Hana (referee)
The bachelor thesis is focused on the analysis of monthly time series of temperatures at nine meteorological stations in Europe between the years of 1951 and 2015. The data were obtained from the database of The European Climate Assessment & Dataset. The geographical position data of chosen stations consist of points in an imaginary grid throughout Europe. The purpose of this bachelor thesis is to compare the development of time series via basic characteristics, to explore the differences due to geographical position and to gain some information about the development of temperature in time via statistical methods. The main object of interest is the location of Praha - Klementinum. Some additional goals are testing the measure of independence of temperatures on the geographical latitude, verifying the continental influence on the climate and checking the shapes of distributions of temperature time series.

The Analysis of Selected Monthly Temperature Time Series in Europe
Janoutová, Eva ; Helman, Karel (advisor) ; Bašta, Milan (referee)
This Bachelor´s thesis is focused on analysis of time series of monthly mean temperatures and monthly maximum temperatures. These temperatures are observed on eight meteorological stations between the years 1949-2013. The data were obtained from the database of European Climate Assessment & Data. Stations are divided into two groups according to Köppen climate classification. The purpose of this bachelor thesis is to observe and compare the development of individual time series in both groups using basic characteristics and methods based on time series decomposition and to verify that the observed station´s climate type classification is correct. Another aim is to verify the hypothesis that monthly mean temperatures and monthly maximum temperatures has increased in the observed period.

Development of seasonality in typical seasonal demographic time series from 1994 to 2014
Bečvářová, Michaela ; Šimpach, Ondřej (advisor) ; Langhamrová, Jana (referee)
This thesis is focused on seasonality in typical demographic time series from 1994 to 2014. The aim of this thesis is to analyse seasonality in monthly time series of live births, deaths and marriages in the Czech Republic and to determine whether seasonality varies in time, whether there can be proven its rise or fall in dependence of changing human habits and traditions respectively. Each demographical process is defined by basic terms and characterized by both absolute and relative indicators. Monthly demographic time series are compared by using average seasonal indexes and further compared for years 1994, 2004 and 2014 by monthly seasonal indexes. The conclusion of this thesis is aimed on comparison of seasonality in time series of Finland and the Czech Republic.

Analysis of monthly precipitation totals from selected monitoring stations in Europe
Krause, Patrik ; Helman, Karel (advisor) ; Kladívko, Kamil (referee)
This thesis is focused on analysis of time series of monthly precipitation totals for four European stations for the years 1913 to 2012. The data were obtained from European database of ECA&D. The aim of this thesis is to find out development of time series and predict precipitation for the year 2013. Prediction of future development of time series is made by using regression modeling of seasonality and Box-Jenkins methodology and the results obtained by the two methods are then compared. The thesis is divided into theoretical and practical parts.

Analysis of temperature time series for selected places in the United States in the years 1964–2013
Libotovský, Patrik ; Helman, Karel (advisor) ; Bašta, Milan (referee)
This bachelor thesis is focused on analysis of time series of monthly average temperatures measured at seven selected meteorological stations located in the territory of the United States in the period 1964-2013. The data were taken from publicly available database US National Climatic Data Centrer. The aim of this work is to determine the evolution of selected time series. Analyzed data are used to obtain findings about the similarities and differences between them. For this analysis, we use basic characteristics and methods based on decomposition of time series to describe the trend and seasonal ingredients. Another aim is to test the hypothesis whether in the monitored period increased the avarage monthly temperature on the territory United States. The thesis is divided into two parts. The first part provides a theoretical description of the selected methods for time series analysis. The second part is devoted to the analysis itself.

Seasonality on selected demographic time series over the last 10 years
Bezchlebová, Daniela ; Šimpach, Ondřej (advisor) ; Bašta, Milan (referee)
Nowadays there is a noticeable trend towards increasing number of children being born out of wedlock -- that is, not in marriage. But the term "marriage" has gained a completely different meaning than in the past. Unmarried cohabitation has become a common alternative to marriage. This is illustrated by the fact that until the end of the 1960s, the proportion of births out of wedlock is very low. The aim of this thesis is to analyse the monthly time series of the number of in-wedlock and out-of-wedlock live births in the Czech Republic over the last ten years, based on selected socio-demographic and technical characteristics, and to prove or reject the statistical significance of the occurrence of seasonal element and further quantify and simulate this element.

Analysis of climatological time series for selected places in Europe in the years 1961-2010
Míka, Tomáš ; Helman, Karel (advisor) ; Bašta, Milan (referee)
This bachelor thesis preoccupied with the analysis climatological time series mesured at seven selected meterological stations located throughout the European continent. The underlying data for this analysis were obtained from publicly available European database of ECA&D. The analysis is focused on calculation of the basic charakteristic and decomposition of time series. The aim of this bachelor thesis is to examine development of the time series of average monthly temperatures and precipation in the period 1961 - 2010 for individual weather stations and these data analyzed to compare with each other and explore similiraties and differences in temperature and precipation from individual station, not only in term of time but also terms of space. This thesis is divided into two parts. The first part is theoretical and generally discribes statistical methods. The second key part (practical) is devoted data processing and analysis of the time series.
