The answer is in the -return list- provided following -ret li-:
. ret li
scalars:
r(n_cent) = 2
r(N) = 74
r(ub_2) = 6232.006871602771
r(lb_2) = 4912.708093501433
r(c_2) = 5705
r(ub_1) = 4679.134062873679
r(lb_1) = 4110.565083233664
r(c_1) = 4424.5
Stata counts from 1, instead of labelling with the centile requested...

hi all,
I'm lit bit confused by centile. for example
************************
.clear
.sysuse auto
. centile price, c(30 60)
-- Binom. Interp. --
Variable | Obs Percentile Centile [95% Conf. Interval]
-------------+-------------------------------------------------------------
price | 74 30 4424.5 4110.565 4679.134
| 60 5705 4912.708 6232.007
*************************
then I want to know the values of centiles, say
*****************************
. di r(c_30)
*****************************
I get missing values.
while
**************************
. di $S_7
4424.5
**********************
so, why r(c_30) doesn't work and why $S_7 works?
thanks,
Guang
