linearities This function calculates the linearities in the negative structure vector matrix X*, so the row vectors for which there is no separation. If this is an empty set or of length 0, then we have overlap.
linearities_acl This function calculates the linearities in the negative structure vector matrix X* for an adjacent-category link model, so the row vectors for which there is no separation. If this is an empty set or of length 0, then we have overlap.
