<P> Time series analysis comprises methods for analyzing time series data in order to extract meaningful statistics and other characteristics of the data . Time series forecasting is the use of a model to predict future values based on previously observed values . While regression analysis is often employed in such a way as to test theories that the current values of one or more independent time series affect the current value of another time series , this type of analysis of time series is not called `` time series analysis '' , which focuses on comparing values of a single time series or multiple dependent time series at different points in time . Interrupted time series analysis is the analysis of interventions on a single time series </P>
