tisane.variable.Nominal¶

class tisane.variable.Nominal(name, data=None, **kwargs)¶

Bases: tisane.variable.Measure

Class for nominal (a.k.a. categorical) measures

Represents a categorical variable. You never instantiate this class directly, and instead you should create instances via the tisane.Unit.nominal() method.

Parameters

name (str) – The name of the categorical variable. If you have data, this should correspond to the column’s name in the data.
data (DataVector, optional) – For internal use only
**kwargs (optional) – Additional keyword arguments from the tisane.Unit.nominal() method, such as categories or cardinality.
