st: one-sided test

[afernandes@worldbank.org]

Hello

I would like to do a very simple test after a linear regression
regress y z1 z2

I want to test if the coefficient on z1 is =1 (null hypothesis) relative to the
possibility of being < 1 (alternative hypothesis).

I did not find any options in the command test to do this.

How can I do this?

Thanks
Ana
