Kielelezo cha Usahihishaji wa Hitilafu wa Vecta wa Fourier (Fourier VECM)

Fourier VECM huongeza kielelezo cha kawaida cha usahihishaji wa hitilafu cha vecta kwa vipengele vya masafa ya chini vya trigonometri — vipengele vya sine na cosine — ili kukamata mabadiliko ya muundo laini, yanayoendelea katika mahusiano ya kukokotoa bila kubainisha idadi au muda wa mapumziko mapema. Hutumika kwa mifumo mingi ya sarafu ambapo usawa wa muda mrefu unaweza kubadilika polepole kwa wakati.
