Muundo wa ARCH wa Fourier (Fourier ARCH Model)

Muundo wa ARCH wa Fourier huupanua mfumo wa kawaida wa ARCH kwa kuingiza vipengele vya trigonometric (Fourier) katika hesabu ya kiwango tofauti cha masharti. Hii huruhusu muundo huo kuelewa mabadiliko laini, yanayoendelea katika mienendo ya tete kwa muda bila kudhani mapumziko makali ya kimuundo, na kuufanya uwe unafaa kwa mfululizo mrefu wa muda wa kifedha au makroekonomi unaokabiliwa na mabadiliko ya utawala yanayoendelea polepole.
