premise: 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 ) .
hypothesis: There is no possible way to classify SKUs , they only have one class and true is true .
