featuretools.primitives.CumSum

class featuretools.primitives.CumSum[source]

Calculates the cumulative sum.

Description:

Given a list of values, return the cumulative sum (or running total). There is no set window, so the sum at each point is calculated over all prior values. NaN values will return NaN, but in the window of a cumulative caluclation, they’re ignored.

Examples

>>> cum_sum = CumSum()
>>> cum_sum([1, 2, 3, 4, None, 5]).tolist()
[1.0, 3.0, 6.0, 10.0, nan, 15.0]
