featuretools.primitives.Diff

class featuretools.primitives.Diff

Compute the difference between the value in a list and the previous value in that list.

Description:

Given a list of values, compute the difference from the previous item in the list. The result for the first element of the list will always be NaN. If the values are datetimes, the output will be a timedelta.

Examples

>>> diff = Diff()
>>> values = [1, 10, 3, 4, 15]
>>> diff(values).tolist()
[nan, 9.0, -7.0, 1.0, 11.0]
