Can anyone offer advice on when to use the index of qualitative variation
(IQV) versus other measures of diversity for ego-centric networks?

Am trying to decide how best to account for group population sizes in
measuring racial/ethnic diversity of survey respondents' networks. IQV was
Marsden's (1987)  choice in analyzing network diversity in the General
Social Survey data on "core discussion networks" of Americans. But the only
methodological citation I can find for IQV is now more than 25 years old
(Agresti and Agresti 1977), and while I'm happy to consult a classic, such
as it is, I'm also hoping for advice based on more recent analytic choices.

Thanks -- Xav
