st: simple question to tests

["Stephan Brunow" <Stephan.Brunow@mailbox.tu-dresden.de>]

Dear Statalist-Readers,

I have a very simple question concerning tests in STATA. I run a regression
and afterwards I did a test for heteroskedasticity. 

. hettest

Breusch-Pagan / Cook-Weisberg test for heteroskedasticity 
         Ho: Constant variance
         Variables: fitted values of yvar

         chi2(1)      =    25.56
         Prob > chi2  =   0.0000

I am (very often) confused, what the probability (here 0.0000) means. Does
it mean that the Ho can not be rejected on a 5 percent level?

Many thanks,

Stephan
