Determines the difference between the max and min value.

Parameters:

skipna (bool) – Determines if to use NA/null values. Defaults to True to skip NA/null.

Examples

>>> max_min_delta = MaxMinDelta()
>>> max_min_delta([7, 2, 5, 3, 10])
8

You can optionally specify how to handle NaN values

>>> max_min_delta_skipna = MaxMinDelta(skipna=False)
>>> max_min_delta_skipna([7, 2, None, 3, 10])
nan
