Laika mainīgo parametru KPSS tests

Laika mainīgo parametru KPSS tests paplašina klasisko Kwiatkowski-Phillips-Schmidt-Shin (1992) stacionaritātes testu uz gadījumiem, kuros sērijas deterministiskās vai stohastiskās komponentes laika gaitā var mainīties. Tas pārbauda stacionaritātes nulles hipotēzi, vienlaikus ļaujot modeļa parametriem attīstīties, padarot to robustu pret strukturālu nestabilitāti, kas citādi izkropļotu standarta KPSS rezultātu.
