st: test that all dummies are jointly not significant

[Oleksandr Shepotylo <shepotil@econ.umd.edu>]

Hi,

I have regression that include 150 dummies and would like to test that
d1+d2+...+d150=0

I can type all 150 dummies in

test d1=-d2-d3-...-d150

but is is very long.

Are there any shortcuts in the test command, or alternative command to 
preform F test that all dummies are jointly not significant?

Thank you, Oleksandr.
