Robust KPSS-test for stationaritet

Den robuste KPSS-test er en udvidelse af den klassiske Kwiatkowski-Phillips-Schmidt-Shin (1992) stationaritetstest, der erstatter den konventionelle estimering af langsigtsvarians med en outlier-robust eller heteroscedasticitets-robust modpart, hvilket bevarer pålidelig størrelse og styrke i nærvær af kontaminerede observationer, strukturelle brud eller ikke-standard fejlfordelinger.
