The Hidden Node Analyzer can be used to identify the number of states of a hidden node. A node is hidden if no case in the dataset contains an observation on the node.
To identify the number of states of a hidden node, the user should specify the hidden node, the minimum number of states, the maximum number of states, and whether the conditional probability table (CPT) of the hidden node should be randomized (default option) as illustrated in Figure 1.
