termCoocDlg: Show co-occurrent terms

Description

Show terms that are the most associated with one or several reference terms.

Details

This dialog allows printing the terms that are most associated with one or several given terms, according to the document-term matrix of the corpus. Co-occurrence is measured by the Chi-squared distance between the (column) profiles of two terms in the matrix: the smaller the distance, the more terms have similar occurrence patterns.

When a variable is selected, the operation is run separately on each sub-matrix constituted by the documents that are members of the variable level. If the term does not appear in a level, NA is returned.

When several terms are entered, the operation is simply run several times separately.
