Time series analysis
Time series analysis – an indispensable tool in monitoring current economic trends
day, time series analysis is an indispensable element in monitoring and forecasting economic trends. This tool permits to adjust the economic time series for influences impairing the detection of the medium to long-term trend of a series. Such factors occurring in the original data may be seasonal influences, calendar influences - such as differing weekday structures per month or quarter, moving holidays, varying school vacations or plant holidays - and extreme or other irregular values which may be caused, for instance, by strikes.
