This statement is the underlying principle of the __time series analysis___ method.

Time series analysis method is a statistical technique that is often employed to determine how a variable changes over a series of time.

Time series analysis has been used in sciences, economics, and mathematics to determine changes of a given data variable over time and in relation to other variables in the same time period.

The wide application of the time series analysis method in various fields is dictated by the need to construct forecasts and make predictions, that is, using past realities to guess future realities.

Thus, this statement that the underlying principle of time series analysis method is based on the fact that past behavior of demand is indicative of its future behavior is widely accepted.
