check out -reshape-. Something like:
reshape wide price, i(week) j(product) string
should do it. You may first want to rename price to price_ if you want the
new price vars to be price_a price_b etc.. instead of pricea priceb...

Subject: st: Reorganize data in STATA
Hi,
I am using Stata 8.0 for Windows.
My problem is the following:
Suppose we have a list with product prices per week like this:
Product week price
a 1 $2
a 2 $2.2
... .... ...
a T $2.1
b 1 $3
b 2 $2.8
... .... ...
b T $2.9
(where we have only one price and week per product and the number of weeks
- T- is the same for all products)
Is it possible to create a table(file) where the number of rows is the #
of weeks and the number of columns is the number of products and we have
the prices series for each product listed "vertically"?, i.e, something
like:
price_a price_b price_c
1 $2 $3 ....
2 $2.2 $2.8 ...
...
T $2.1 $2.9 ....
Is there an easy way to do this in STATA?
I would really appreciate some help on this...
Thanks,
MA
