featuretools.primitives.NumConsecutiveLessMean#

class featuretools.primitives.NumConsecutiveLessMean(skipna=True)[source]#

Determines the length of the longest subsequence below the mean.

Description:

Given a list of numbers, find the longest subsequence of numbers smaller than the mean of the entire sequence. Return the length of the longest subsequence.

Parameters:

skipna (bool) – If this is False and any value in x is NaN, then the result will be NaN. If True, NaN values are skipped. Default is True.

Examples

>>> num_consecutive_less_mean = NumConsecutiveLessMean()
>>> num_consecutive_less_mean([1, 2, 3, 4, 5, 6])
3.0

We can also control the way NaN values are handled.

>>> num_consecutive_less_mean = NumConsecutiveLessMean(skipna=False)
>>> num_consecutive_less_mean([1, 2, 3, 4, 5, 6, None])
nan
