De student had zijn besluit nog iets gedetailleerder kunnen formuleren.

Kledingproductie / totale productie: Yt / Zt = c

Yt = c . Zt

De lange termijn evolutie van totale productie zou gelijk lopen met de lange termijn evolutie van kledingproductie, indien c positief is en het model klopt.

Er is geen constante, want we hebben te maken met een dalend verloop. Dit kunnen we zien aan de Run Sequence Plot-grafiek. Er is een fundamenteel probleem met de kledingproductie. De totale productie en de kledingproductie lopen dus niet gelijk. Het model klopt niet. De totale productie groeit sterker dan de kledingproductie.

een iets uitgebreidere analyse had welkom geweest. De totale productie staat in de noemer, als die sneller groeit dan wat er in de teller staat dan krijgt men steeds kleinere waarden ==> dalende trend.
