featuretools.primitives.MaxCount#

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

Calculates the number of occurrences of the max value in a list

Parameters:

skipna (bool) – Determines if to use NA/null values. Defaults to True to skip NA/null. If skipna is False, and there are NaN values in the array, the max will be NaN regardless of the other values, and NaN will be returned.

Examples

>>> max_count = MaxCount()
>>> max_count([1, 2, 5, 1, 5, 3, 5])
3

You can optionally specify how to handle NaN values

>>> max_count_skipna = MaxCount(skipna=False)
>>> max_count_skipna([1, 2, 5, 1, 5, 3, None])
nan
