Web13 mei 2024 · Downloadable! kpss performs the Kwiatkowski, Phillips, Schmidt, Shin (KPSS, 1992) test for stationarity of a time series. This test differs from those in common use (such as dfuller and pperron) by having a null hypothesis of stationarity. The test may be conducted under the null of either trend stationarity (the default) or level stationarity. WebKPSS Test Specification. Unlike unit root tests, Kwiatkowski et al. provide straightforward test of the null hypothesis of trend stationarity against the alternative of a unit root. For this, they consider three-component representation of the observed time series as the sum of a deterministic time trend, a random walk and a stationary residual:
