tisane.variable.Ordinal¶

class tisane.variable.Ordinal(name, order, cardinality=None, data=None)¶

Bases: tisane.variable.Measure

Represents ordinal measures

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

Parameters

name (str) – The name of the ordinal variable. If you have data, this should be the column name in the data.
order (list) – The ordering of the categories of the variable
cardinality (int, optional) – The number of unique values for the variable. This should equal the length of order.
data (DataVector, optional) – For internal use only.
