KPSS test sa vremenski promenljivim parametrima
KPSS test sa vremenski promenljivim parametrima proširuje klasični test stacionarnosti Kwiatkowski-Phillips-Schmidt-Shin (1992) na situacije gde se determinističke ili stohastičke komponente serije mogu menjati tokom vremena. On testira nultu hipotezu stacionarnosti, istovremeno dozvoljavajući parametrima modela da evoluiraju, čineći ga robusnim na strukturnu nestabilnost koja bi inače iskrivila standardni KPSS rezultat.
