Enum: PolaritySemantics

Whether the sign of a component map carries meaning. Decomposition methods can return components whose polarity is arbitrary, in which case a negative loading is not a decrease.

Permissible Values

Value Meaning Description
meaningful None The sign is interpretable: a negative value means a decrease
arbitrary None The method could have returned the component with its sign flipped, so a nega...
