Furjē OLS (Furjē papildinātais parastais mazāko kvadrātu metodes)

Furjē OLS ir OLS regresija, kas paplašināta, pievienojot zemas frekvences trigonometriskus (sinusa un kosinusa) locekļus regresoru matricai. Šie Furjē komponenti aptuveni attēlo gludas, pakāpeniskas strukturālās izmaiņas regresijas sakarībā laika gaitā, neprasot zināšanas par pārtraukumu skaitu, laiku vai formu.
