featuretools.primitives.MaxConsecutiveZeros

class featuretools.primitives.MaxConsecutiveZeros(skipna=True)

Determines the maximum number of consecutive zero values in the input

Parameters:

skipna (bool) – Ignore any NaN values in the input. Default is True.

Examples

>>> max_consecutive_zeros = MaxConsecutiveZeros()
>>> max_consecutive_zeros([1.0, -1.4, 0, 0.0, 0, -4.3])
3

NaN values can be ignored with the skipna parameter

>>> max_consecutive_zeros_skipna = MaxConsecutiveZeros(skipna=False)
>>> max_consecutive_zeros_skipna([1.0, -1.4, 0, None, 0.0, -4.3])
1
