## Time Series Differencing

Time series differencing is a transformation method used to stabilize the mean of a time series by removing changes in the level of the series. This is achieved by subtracting the previous observation from the current observation, effectively focusing on the changes or returns rather than the raw price levels.

In cryptocurrency finance, log returns are often used as a form of differencing to normalize data for volatility and trend. This process is essential for making non-stationary price data stationary so that statistical tools like correlation and regression can be applied without yielding spurious results.

If a series is integrated of order one, a single round of differencing is usually sufficient to achieve stationarity. This technique is a cornerstone of ARIMA modeling, which is widely used for short-term price forecasting.

By isolating the period-to-period change, traders can better identify underlying market dynamics that are obscured by long-term price trends. It is a simple yet powerful tool for cleaning financial data before quantitative processing.
