st: 'test' after GLM with robust cluster option

[<lm335@drexel.edu>]

Dear Statalisters,
                  I am using GLM with robust estimation of standard error in an analysis. In this context, is it legitimate to use the 'test' command to conduct a test of global usefulness of the form
  test b1=b2=b3=0

I'd appreciate any comments on this.

Thanks

Leny
