Dear Listers,

   Just the following simple and naive question

  How can i perform a one sided test after a linear regression?

  after this regression
        regress y x1 x2
  i want to test if the coefficient of x2 is greater than 0

thanks a lot

Levy
In addition to what Joe suggests, just look at the printout, and see (a) is the coefficient for x2 positive, and (b) is it significant at the .10 level (or double whatever alpha level it is you want to chose). You don't need to do any additional analyses, the information you need is already there.
