We classify the SKUs into three  those with high demand (averaging 5,700 units a week) and low demand variation (Cv=0.6), those with medium demand (averaging 3,000 units a week) and medium demand variation (Cv=0.7), and those with low demand (averaging 1,300 units a week) and high demand variation (Cv= 1.3).

There is no possible way to classify SKUs, they only have one class.
