featuretools.primitives.CumMin#
- class featuretools.primitives.CumMin[source]#
Calculates the cumulative minimum.
- Description:
Given a list of values, return the cumulative min (or running min). There is no set window, so the min 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_min = CumMin() >>> cum_min([1, 2, -3, 4, None, 5]).tolist() [1.0, 1.0, -3.0, -3.0, nan, -3.0]
