Node Indicators

Context

• In BayesiaLab's Graph Panel, nodes can be tagged in a number of ways to display certain attributes and conditions.

Warnings & Errors

• — The Warningicon can indicate a number of issues:
  • The formula in the Formula Editor is not validated or incorrect.
  • The Conditional Probability Table associated with the node has not been specified, e.g., it is blank or incomplete.
  • At least in one row of the Conditional Probability Table associated with the node, the probabilities do not sum to 100%.
• — The Error icon means that, after modifying its parent nodes, the formula in the Formula Editor is no longer correct.
• Press i while holding your cursor over the node displays the corresponding warning or error message.

Indicator Icons

• With Indicator Icons, you can quickly see key attributes of nodes, without having to open the Node Editoror bringing up Monitors.
  • — a Cost other than the default value of 1 is defined for the node.
  • — an Expert Assessment is associated with this node. The stronger the divergence (variance) between the assessments for this node, the darker the background of the icon. Pressing while hovering on the icon displays the following information:
    • the number of conditional probability table's rows with assessments compared to the total number of rows
    • the total number of assessments
    • the number of experts involved compared to the total number of experts
    • the overall divergence
    • the maximum divergence
  • — one of the node's states is defined as a Filtered State.
  • — the node is Hidden. It represents a latent variable that does not have associated data.
  • — a Local Structural Coefficient, other than the default value of 1, is applied to the node.
  • — the data associated with the node contains missing values. Press i while holding your cursor over the icon to display the number of missing values.
  • — the node is Not Observable, i.e., Cost=0.
  • — one of the node's states is defined as a Reference State.
  • — Stratification is applied to the node.
  • — a Temporal Index is defined for the node.
  • — the node's Conditional Probability Distribution is estimated with Conditional Probability Trees.
  • — the node contains Virtual States.
  • — a Comment is associated with the node. Press i while holding your cursor over the icon to display the Comment.
• You can turn off the Indicator Icons by clicking the Hide Information button  or by selecting Main Menu > View > Hide Information from the Menu Bar.
