Theta-metoden

Theta-metoden er en univariat tidsserieprognosemodel introduceret af Assimakopoulos og Nikolopoulos i 2000. Den nedbryder en serie i to theta-linjer, der fanger dens langsigtede trend og dens kortsigtede dynamik, prognostiserer hver linje separat og kombinerer dem ved et vægtet gennemsnit. Dens enkelhed og nøjagtighed gjorde den til vinderen af M3-prognosekonkurrencen.
