conindex results not matching?

[Mayank Agrawal]

Dear all,

I want to calculate concentration index as a part of research project.

First, i did the calculations using the package conindex and got a value of -0.026. After that i did the calculations using the code given by Owen O' Donnell et. al. in their book and i got a value of -0.122 which is comparable to the earlier published literature.

Why this difference and how can this be interpreted?
I am using negative of HAZ scores (removed the flagged values) as the dependent variable and health index score as the ranking variable in both the calculations. I am using DHS 15-16 for India.

I used the following code:
conindex neghaz, rankvar(wis) bounded limits (-6 6) svy

What is the mistake that i am doing?

Thanks in advance!!

(This kind of question with no example data, use of a community-contributed program you don't explain, and a cryptic reference (which book is that? why are we supposed to know about it?) often gets little or no reply, but there was more detail in the first post, another reason to go there.)
