How to make Kpss test in Excel
The KPSS (Kwiatkowski-Phillips-Schmidt-Shin) test is a statistical test used to check for the stationarity of a time series around a deterministic trend. Unlike the Augmented Dickey-Fuller (ADF) test, which tests for unit roots, the KPSS test assumes that the series is stationary around a trend and tests against the null hypothesis of stationarity. Conducting a KPSS test in Excel requires a series of steps, as Excel does not have a built-in function for this specific test. However, you can perform the test by manually calculating the necessary statistics or using Excel’s capabilities for statistical analysis with some setup.
