Time series stationary
Did you know?
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 d… WebTrend stationarity. A stochastic process is trend stationary if an underlying trend (function solely of time) can be removed, leaving a stationary process. Meaning, the process can be …
WebOptimum non-parametric tests for stationarity of a stochastic process against location and scale shift alternatives are explored. Usefulnesss of these tests in detecting a suitable differencing transformation that reduces a non-stationary time series to a stationary one is illustrated with a number of previously analysed real life data.
