stationary test 檢驗數據是否為穩定 藉此判定ARIMA程序中的d值-stationary test

2 matlab files, combining to perform the Augmented Dickey-Fuller unit root test in Matlab. Useful for detecting auto-correlations and check for stationarity in time series, check for spurious regression, etc.

时间序列算法，平稳性检验，采用matlab编程对数据序列的稳定性作出相应的判断(ime series algorithm, stationarity test, using MATLAB programming to determine the stability of the data sequence)
