Dear all,
Suppose we want to limit observations where one variable records a larger value
than its top quartile, we can write as follows.

sum d,detail
reg y a b c if d>r(p75)

However, this program allows only fixed thresholds such as 1, 10, and 75 percent.
How can I use other thresholds such as r(p33) in the program?
Or, is there any program to do the same?
Thanks in advance.
