In mathematics and statistics, a stationary process (or a strict/strictly stationary process or strong/strongly stationary process) is a stochastic process whose unconditional joint probability distribution does not change when shifted in time. Consequently, parameters such as mean and variance also do not change over time. If you draw a line through the middle of a stationary process then it should be flat; it may have 'seasonal' cycles, but overall it does not trend up nor … Witryna24 lis 2024 · ADF test is the most commonly used test the Stationarity of the series, where the null hypothesis is the time series possesses a unit root and is non-stationary.
