See my post from yesterday with the same question.

You can get the same results, I believe, with test using the second syntax, which will test the hypothesis that all coefficients are equal to zero and give you the F (k, n) and Prob > F results.

Dear Statalisters:

I'm running simple OLS regressions with robust standard errors.
In some cases the F-stat of the regression and Prob>F are reported as a dot
".", like in the example below.
The problem does not show up if I run the same regression without robust
standard errors.
Can someone tell me what can be going on here?

Regression with robust standard errors                 Number of obs =
                                                       F( 25,  1148) =
                                                       Prob > F      =
                                                       R-squared     =
                                                       Root MSE      =
