Kpss data

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:. If the null hypothesis in failed to be rejected, this test may provide evidence that the series is non-stationary. KPSS is another test for checking the stationarity of a time series. Based upon the significance level of 0.

Indicates the number of lags to be used. The p-value of the test. The p-value is interpolated from Table 1 in Kwiatkowski et al. The p-values are interpolated from Table 1 of Kwiatkowski et al. If the computed statistic is outside the table of critical values, then a warning message is generated.

A KPSS test can be used to determine if a time series is trend stationary. This test uses the following null and alternative hypothesis:. If the p-value of the test is less than some significance level e. We can use the kpss function from the statsmodels package to perform a KPSS test on this time series data:. The p-value is 0. Since this value is not less than. This means we can assume that the time series is trend stationary. Note 1 : The p-value is actually even greater than 0. Once again, we can use the kpss function from the statsmodels package to perform a KPSS test on this time series data:.
