The point is made in the Statalist FAQ, which you were asked to read
before posting.

Hi,

I have used the following commands to estimate the concentration index.

glcurve income [aw=weight], pvar(rank) nograph
qui sum yis [fw=intweight]
scalar mean=r(mean)
cor yis rank [fw=intweight], c
sca c=(2/mean)*r(cov_12)
sca list c

Kindly let me know how to derive confidence interval for the concentration
index calculated using the above STATA commands.
