Ik denk dat normaalverdeling een goede benadering is voor Yt. Op de grafiek worden de echte waarden weergeven door het histogram en de geschatte waarden door de curve. Je kan zien dat het histogram zeer goed overéénkomt met de curve. Je kan dus concluderen dat de normaalverdeling een zeer goede benadering is voor Yt.
