featuretools.primitives.AverageCountPerUnique

class featuretools.primitives.AverageCountPerUnique(skipna=True)

Determines the average count across all unique value.

Parameters:

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

Examples

Determine the average count values for all unique items in the input >>> input = [1, 1, 2, 2, 3, 4, 5, 6, 7, 8] >>> avg_count_per_unique = AverageCountPerUnique() >>> avg_count_per_unique(input) 1.25

Determine the average count values for all unique items in the input with nan values ignored >>> input = [1, 1, 2, 2, 3, 4, 5, None, 6, 7, 8] >>> avg_count_per_unique = AverageCountPerUnique() >>> avg_count_per_unique(input) 1.25

Determine the average count values for all unique items in the input with nan values included >>> input = [1, 2, 2, 3, 4, 5, None, 6, 7, 8, 9] >>> avg_count_per_unique_skipna_false = AverageCountPerUnique(skipna=False) >>> avg_count_per_unique_skipna_false(input) 1.1
