Table Dialog Box

Purpose:  You use the Table Dialog Box to enter, change or view the relationship of a node with its parents (i.e. its CPTs).  Choosing which nodes are going to be the parents is not done with this dialog box, but rather by adding links.  A node does not specify a relation with its child nodes, since those relations are specified at the child nodes.  If you want the relation to be specified by an equation, or if you want to change the properties of a node (e.g. its name, or what states it has), use the node dialog box instead.

Obtaining:  Obtain a table dialog box for a node by selecting it, and then choosing Table → View/Edit, clicking the tool button with the relation symbol: , or by right-clicking on the node and choosing Table.

Table:  The relationship is expressed in the form of a table.  The following describes what the table entries mean, how to change them, how to select, copy and paste them, how to scroll and resize the table, and how to reorder its columns.

Kinds of Tables:  The table dialog box can be used to view or edit several different kinds of tables for the node, which you choose with the table selector. The node's function table or conditional probability table (CPT) are the most commonly used, but if you have Netica learning from data or connecting to a database, then its experience table, unnormalized probability table and counts table will be of interest.

Controls:  Making a change within the dialog box does not affect the node until the correct button is pressed.  There are selectors to choose the node to work on, and to make it deterministic or probabilistic.  There are several menu commands that can modify the table.

Multiple:  You may have several table dialog boxes on the screen at the same time, and you may alternate between using different table dialog boxes, different node dialog boxes, and working directly in the net window.  To use one of the table dialog boxes it must be the active window.  You may even have more than one table dialog box for the same node.
