Statistická analýza vztahů mezi časem věnovaným vybraným mediatypům

Nowadays, about a third of the average person's day is spent on one of the electronic media, regardless if it is television, computer or mobile phone. This is confirmed by the fact that over the past few years, the printed media have been retreating to the electronic media. Electronic media include television, radio and the internet. Since the time spent with these media is constantly growing, this thesis will focus on what this is caused by.There are two main options to consider, either this development is due to the massive displacement all the media by one media or increasing amount of time spent on all media, only to a lesser extent. In the thesis, these two possibilities were considered using linear regression (for models of the relationship between two time series), or by VAR models (for models of the relationship between three time series). The result of the investigation confirmed the theory that indicates a slight increase in time devoted to each of the media.
