Determines the maximum number of consecutive negative values in the input

Parameters:

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

Examples

>>> max_consecutive_negatives = MaxConsecutiveNegatives()
>>> max_consecutive_negatives([1.0, -1.4, -2.4, -5.4, 2.9, -4.3])
3

NaN values can be ignored with the skipna parameter

>>> max_consecutive_negatives_skipna = MaxConsecutiveNegatives(skipna=False)
>>> max_consecutive_negatives_skipna([1.0, 1.4, -2.4, None, -2.9, -4.3])
