Dear all
I am trying to use the command "pctile" to get percentiles of the values
in a variable. The values are individual ages.
I have used the commands:
pctile pct=age
pctile pct=age, genp(pctAge)
but when I run it and then list the first 10 instances I get
. list pct age in 1/10
pct age
1. 9 14
2. . 17
3. . 1
4. . 14
5. . 5
6. . 12
7. . 14
8. . 7
9. . 9
10. . 0
The ages run from 0 to 17 and are fairly evenly distributed.
?? Why don't I get any values in the pct column and what does the '9' mean.
Many thanks for any help.
