In this case, Stata does state the null hypothesis. So if you are willing to
be wrong at least 2 out of 100 times while interpreting this test statistic,
reject the null (which does not necessarily mean acceptance of the
alternative). If you are only willing to be wrong 1 out of 100 times or
less, don`t. Bottom line: There is nothing specific about this test that
would distinguish it from any other test.

Betreff: st: ST: Ramsey test interpretation
Dear all,
I am sorry to ask such a basic question, but I always have a doubt when
interpreting the results of the ovtest:
I the output of the ovtest says:
"Raymsey test using the powers of the fitted value of the dependent
Ho: model has no omiited variable
F (3, 168) =3.43
Prob > F = 0.0169"
What should I conclude? Does the model suffers from ommitted variables or
not?
Thanks,
Laura
