Analýza sezónnosti časových řad úmrtnosti dle příčin smrti v České republice

The main aim of this diploma thesis is to describe seasonality in time series of mortality according to causes of death in the Czech Republic in the years 1968–2015. In addition, the reader will generally approach the methods by which seasonality can be detected, measured and described in time series. The work focuses mainly on seasonal mortality on respiratory diseases and neoplasms. However, the seasonality of mortality is also briefly described for other causes of death. The work focuses mainly on the number of deaths during the year and the seasonal changes that occurred during the reporting period. I use various types of graphical tools for the analyze. Additionally, time series are divided into individual components by decomposition method and the then attention is focused on seasonality. The analysis shows that for most causes of death people die more frequently in the winter than in the summer months. The exception is the external causes of morbidity and mortality. The largest differences in the number of deaths between months of the year are in respiratory diseases, while in neoplasms the seasonality is very weak. Despite the changes that occurred in the internal structure of these groups of causes of death, there were no major changes in the size and seasonality during the reporting period. Based on these conclusions, it is possible to create more accurate population projections and forecasts and to better target preventive care programs.
