I think that Shuaizhang would like to calculate centile using
another command that - centile (maybe He has a complex design or other
kind of dataset) - "I know you can calculate the percentiles for y
using "centile", but how do you go the other way?". I always use
centile and I didnt replay because I didnt think other way to do this.
Could you explain better Shuaizhang?
