categories

This module gathers structure used to define categories.

class BoundedCategoryProfile(lower=None, upper=None)

Bases: object

This class represents a category defined by profiles as its limits.

Parameters

Raises

ValueError – if upper doesn’t dominate lower

classmethod profiles_partition(profiles, lowest=True, upmost=True)

Build a list of bounded category profiles.

Parameters

profiles (PerformanceTable[OrdinalScale]) –
lowest (bool) – if True add a category profile with last profile as its upper bound (and no lower bound)
upmost (bool) – if True add a category profile with first profile as its lower bound (and no upper bound)

Raises

ValueError – if any profile doesn’t dominate its predecessor

Returns

list of bounded category profiles in ascending domination order

Return type

List[BoundedCategoryProfile]

class CentralCategoryProfile(center)

Bases: object

This class represents a category defined by a central profile.
