Siklos

Siklos is a statistical test used in time series analysis to detect whether a series exhibits stationarity or contains a unit root, indicating non-stationarity. Essentially, it helps determine if the data's properties, like mean and variance, stay consistent over time or if the series has a trend or change in behavior. This is important because many forecasting models require stationary data to produce reliable predictions. The Siklos test is similar to the Augmented Dickey-Fuller test but adjusts for certain patterns, making it useful in analyzing economic and financial data to decide on appropriate modeling strategies.
