Dissimilarity index --------------------
^dissim^ varlist [^if^ exp] [^in^ range] [ ^,^ ^m^atrix^(^matname^)^ ]
Description ------------
^dissim^ displays the dissimilarity index D for each pair of variables in varlist. If x and y are >= 0, form the proportions
p = x / SUM x and q = y / SUM y
and calculate D = 1/2 SUM ( | p - q | ). D lies in [0, 1].
Options --------
^matrix(^matname^)^ specifies that results are to be placed in matrix matname.
Examples ---------
. ^dissim a b c^
