```Hallo everyone, I am new in stata. I am using STATA 9.2. I do have a
very basic statement on how to generate a variable which is equal to
the lowest 10th percentile of income(Dy) ?
I tried this:
sort Dy
Xtile deciles = Dy, n(10)
forvalues `i' = 1/20 {
bys deciles : egen CC`i' =mean (C`i' )
}
This seem to do part of the job. But it gives me mean of all deciles.
For example CC1 varies from decile 1-10 as follows:
Deciles                    CC1               CC2
CC3..............................................
1                              333                440
1                              333                440
1                              333                440
2                              605                777
2                              605                777
2                              605                777
2
..
..

As a next step i now want to create a new variable which only uses
mean of the lowest decile  for all variables e.g CCC`i'= mean of
decile 1  for all observations. To be more precise i want CCC1 to be
equl to 333 for all observation, and CCC2 to be 440 etc I know i can
do this manually by checking value of CC`i'  when decile=1 , and then
proceed to input values:

generate CCC1 = 330

generate CCC2=  440

.         .

.         .

etc up to 20th item.
I was just wondering if there is a way of doing it automatically in my
do file without stoping and checking results and inputting them
manually, because i do have a lot of variables, even more than 20?
