Learning Wizard
===============

To get assistance in the process of learning a Bayesian-network model from data, the Learning Wizard can be quite useful.  The Learning Wizard can be invoked from the "Wizards" item of the menu bar of the :ref:`Main Window<main_window>`.

The Learning Wizard read data from a plain text file, provides a :ref:`data matrix<data_matrix>` for editing and :ref:`preprocessing of the data<data_processing>` in different ways (e.g., variable exclusion, value replacements, and discretization). The wizard also enables you to provide any structural or distributional domain knowledge that you might have, to resolve any structural uncertainties resulting from the :ref:`NPC learning algorithm<NPC_Algorithm>`, to investigate the strengths of the dependences found in the data, and to provide prior knowledge about the conditional probability distributions.

For more detailed information on the Learning Wizard, please consult the online help pages provided with the Learning Wizard.
