WebNov 2, 2024 · KPSS test is a statistical test to check for stationarity of a series around a deterministic trend. Like ADF test, the KPSS test is also commonly used to analyse the stationarity of a series. However, it has couple of key differences compared to the ADF test in function and in practical usage. WebDec 21, 2024 · To run the ADF test in R software, we use the following function "adf.test (Data, nlag=Null, Output=True)" Where Data represent the time series to be tested, nlag is the number of lags to consider and Output is an option for printing the results in the R console. In order to run the test, we need to call the package "tseries" in the library of R.
