Stationarity means that the statistical properties of a time series i. Many statistical models require the series to be stationary to make effective and precise predictions. A method to convert a non-stationary time series into stationary series shall also be used. Sunspots dataset is used. It contains yearly data on sunspots from the National Geophysical Data Center. ADF test is used to determine the presence of unit root in the series, and hence helps in understand if the series is stationary or not. The null and alternate hypothesis of this test are:.

KPSS test is a statistical test to check for stationarity of a series around a deterministic trend. However, it has couple of key differences compared to the ADF test in function and in practical usage. Therefore, is not safe to just use them interchangeably. A common misconception, however, is that it can be used interchangeably with the ADF test. This can lead to misinterpretations about the stationarity, which can easily go undetected causing more problems down the line.

In econometrics , Kwiatkowski—Phillips—Schmidt—Shin KPSS tests are used for testing a null hypothesis that an observable time series is stationary around a deterministic trend i. Contrary to most unit root tests , the presence of a unit root is not the null hypothesis but the alternative.
