Re: st: forvalues, panel data

[David Kantor <kantor.d@att.net>]

Putting aside the -forvalues- issues, which were addressed in another 
response by Nick Cox, you may be interested in my -cpiadj- program 
for doing cpi-adjustments. This covers the U.S. cpi (Consumer Price 
Index) from 1976 through 2004, though it could certainly be enhanced 
to cover the latest available years. It does the general all-items, 
all-US-consumers flavor, plus several others (food, shelter, etc.).
If you are interested, write to me privately. This has not been made 
public, but if there is interest, I would consider publishing it.
