Aikaeromenetelmässä
Aikaeromenetelmässä, often translated as the "time difference method" or "time lag method," is a technique used in various fields, particularly in signal processing and econometrics, to analyze relationships between two or more time series. The core principle involves examining how a change in one variable or signal precedes or follows a change in another. This is achieved by systematically shifting one of the time series by different time lags and measuring the degree of correlation or other forms of association at each lag.
The application of aikaeromenetelmässä is diverse. In economics, it's used to identify leading or lagging indicators,
The process typically involves calculating a cross-correlation function between the two time series. The lag at
