PRODUCT Variability of invoice Weekday based on item TotalCost 28d
SDK code to create PRODUCT_Variability_of_invoice_Weekday_based_on_item_TotalCost_28d¶
Feature description:
The feature evaluates the distribution of a product's item's TotalCost across various invoice's Weekday categories over a 28d period using entropy. Higher entropy signifies a more uniform distribution of item's TotalCost across categories, while lower entropy suggests a concentration within specific invoice's Weekday categories.
