We gaan Lambda introduceren om zo de variantie gelijk te krijgen. Het Standard Deviation Plot gaat na of de spreiding afhankelijk is van het niveau van de tijdreeks. In de eerste tabel staat de vergelijking van de regressielijn die we door de punten van de grafiek kunnen tekenen geschreven. In de 2e tabel  staat diezelfde regresievergelijking maar dan in de logaritmische vorm.
