Fourier fiks-efektide mudel

Fourier fiks-efektide mudel laiendab standardseid paneeli fiks-efektide regressioone, täiendades spetsifikatsiooni madalsageduslike Fourier' (trigonomeetriliste) terminitega. Need siinus- ja koosinuskomponendid ligikaudustavad tundmatuid, sujuvaid struktuurseid nihkeid ajatrendis, ilma et uurija peaks katkestuskuupäevi eelnevalt määrama, ühendades ühikusisest identifitseerimist paindliku trendi modelleerimisega.
