Hi,

I'm clustering objects and want to be able how "good" (homogeneous) is the clustering.
inconsistent() (described in http://www.mathworks.com/access/helpdesk/help/toolbox/stats/inconsistent.html)
provides me with an "Inconsistency coefficient" which seems to be what I'm looking for.
However there seems to be a mistake in the documentation. Shouldn't
Y(k,4) = (z(k,3) - Y(k,1))/Y(k,2)
be
Y(k,4) = (Y(k,3) - Y(k,1))/Y(k,2)
?
I don't understand where the "z" came from, and since the table above describes the 4 columns of Y I assume it should be "Y" instead of "z".

If indeed it is meant to be "z", can you explain me what this value describes?
