Subject   st: Difference of means and t-test

Dear Statalist,

I am working with three different samples.
When I deal with two of them, I can calculate the difference of means and
t-test by doing:

ttesti obs1 mean1 std1 obs2 mean2 std2, unequal

As I have three groups, I am also interested in testing the null: mean1 =
mean2 = mean3 , under the alternative that at least one mean is different.

Could you please give me some advice?

Thanks in advance.
