März 2010 23:16 To: statalist@hsphsun2.harvard.edu Subject: st: generate 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?
