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.

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 python, the statsmodel package provides a convenient implementation of the KPSS test. So practically, the interpretaion of p-value is just the opposite to each other. Whereas in ADF test, it would mean the tested series is stationary.
