   :alt: Usage example

Classifier chain learner takes a single-target learner and with it creates a classifier for every class variable in the data. Every time a classifier is created, the values of that class variable are added to features. The order in which the class variables are chosen is random.


Setting:
--------
- Use actual values
	If checked, the values added into features are actual values from the data. Otherwise the values predicted by the classifier are used.
