st: how to calculate the Standardized Duncan Index by duncan or duncan2 command?

["Simo Hansen" <simohansen@gmail.com>]

Dear All,
In the segregarion literature, some researchers suggest to use "standardized
Duncan index". Can I use the duncan or duncan2 command with some options to
obtain the standardized Duncan index? Or Should I calculate this
standardized one by writing a small program?
Thanks for your kind concern in advance.
Simo
