Re: st: Questions about -rspread-

I am the original author of rspread

I was out of the office all day yesterday, so I only seeing the messages today.

I tried -rspead- on the auto data and had no problems (Stata 9 in Windows XP) 
so am not sure what is going on.  However, it is also the case the Nick Cox 
very generously took on the re-writing, and bringing up to date, of the 
program and this should appear in a forthcoming SJ -- much thanks to Nick

The answer to question 2 is "no" -- the program was never meant to overlay 
Lorenz curves directly
