featuretools.primitives.CumMax

class featuretools.primitives.CumMax[source]

Calculates the cumulative maximum.

Description:

Given a list of values, return the cumulative max (or running max). There is no set window, so the max 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_max = CumMax()
>>> cum_max([1, 2, 3, 4, None, 5]).tolist()
[1.0, 2.0, 3.0, 4.0, nan, 5.0]
