atoti.agg.sum_product(*factors: MeasureConvertible, scope: Scope) → MeasureDescription

Return a measure equal to the sum product aggregation of the passed factors across the specified scope.

Parameters:

  • factors – The factors to multiply together and then aggregate as a sum.

  • scope – The scope of the aggregation.

Example

>>> from datetime import date
>>> df = pd.DataFrame(
...     columns=["Date", "Category", "Price", "Quantity", "Array"],
...     data=[
...         (date(2020, 1, 1), "TV", 300.0, 5, [10.0, 15.0]),
...         (date(2020, 1, 2), "TV", 200.0, 1, [5.0, 15.0]),
