The KPSS test is based on linear regression. It breaks up a series into three parts: a deterministic trend (βt), a random walk (rt), and a stationary error (εt), with the regression equation: If the data is stationary, it will have a fixed element for an intercept or the series will be stationary around a fixed … Meer weergeven The Kwiatkowski–Phillips–Schmidt–Shin (KPSS) test figures out if a time series is stationary around a mean or linear trend, or is non-stationary due to a unit root.
