Oleksandr,
The command you're looking for is called testparm.
In your case: testparm d1-d150
That should do the trick.
Best,
Tom Kovandzic

Subject: st: test that all dummies are jointly not significant
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.
