Documents/Variables Dissimilarity Table
Description
Build a dissimilarity table reporting Chi-squared distances between documents and/or levels of a variable.
Details
This dialog can be used in two main ways. If "Document" or one variable is selected for both rows and columns, the one-to-one dissimilarity between all documents or levels of the variable will be reported. If a different variables are chosen for rows and for columns, a cross-dissimilarity table will be created; such a table can be used to assess whether a document or variable level is closer to another variable level.
In all cases, the reported value is the Chi-squared distance between the two documents or variable levels, computed from the total document-term matrix (aggregated for variables).
