Dear statalists,
I want to generate a new variable equaling 1 if the other variable is greater than its 100/3 percentile and 0 otherwise.How to get the 100/3th percentile of a variable?
And how does Stata calculate percentiles if the number of observations is odd or even?
Additionally, what does the output "smallest and largest" mean after "su varname,d"?
Thanks!
