Dear Statalisters,
Do you know any a faster way of doing what ^xtile^ command does?
Let me explain my problem:
I have a variable, say X, with 50k observations, and a frequency
weights, say W, which is on average 6k. I need to generate a new
variable that categorizes X by a large number of quantiles (40k).
I need something that ideally ^xtile^ command does but it takes ages.
My command line for variable X is:
xtile double pc = X [fw = W]. nq(40000)
I guess the problem is that xtile is written as an ado file without
using Mata and it loops forever and ever.
Many thanks for your help!
Luigi
