The implication is that you already have a variable called -deciles-. -xtile- expects to be given a new variable name. See the help for -deciles- again.

I have panel data (sorted firmID and financial year).
For my regression I need to select firm-years, according to asset size,
that is in top three and bottom three deciles.
For this purpose I followed your instructions (Decile sorts,
http://www.stata.com/statalist/archive/2006-11/msg00309.html) and
applied the following solution:
. foreach X of varlist dat* {
2. xtile deciles=`X', n(10)
3. }
deciles already defined
why did I get "deciles already defined" message in red.
And is that correct code or should I modify it?
