Kit Baum`s article at
http://www.stata-journal.com/sjpdf.html?articlenum=st0080 should be a good
point of entry for you.
Who are you adressing in your intro, BTW?

Subject: st: stata help
Hi
I was doing some chearch queries concerning how to apply structural unit
roots tests in stata and I found your email in some online emails.I am a
master's student at gothenburg university doing my thesis on cointegration
between fertilizers and gas.
I am wondering if you can help me finding out how to perform unit roots
tests mainly the two steps procedures of Perron (1992) when time series
have at least two known structural breaks.
Another question is how I can define the trend in STATA. Actually I want
to perform a normal OLS regression using a trend and a constant but I cant
find how to include the trend in Stata. Maybe be i will need to create it
but how?? any help!
thank you in adavnce
