Dear Maarten,
Thank you very much. I have not used centile command until now. I will definitely try it out.
Thanks.
Best regards,
Swati Misra.

You can get these values with the -centile- command, see -help
centile-, which will also store these values in r(c_1), r(c_2), etc,
depending on how many centiles you asked for. You can then use these,
for instance in the -xline()- option, which I think makes more sense
than adding them as data points, because these values only contain
information on x, while an data point also implies information on the
y-value.
*----------------- begin example -----------------
sysuse auto, clear
centile trunk, c(2.5 97.5)
scatter� weight trunk, xline(`r(c_1)' `r(c_2)')
*----------------- end example -------------------
(For more on how to use examples I sent to the Statalist, see
http://home.fsw.vu.nl/m.buis/stata/exampleFAQ.html )
Hope this helps,
Maarten
