```Hi,

I am new to Stata and Econometrics.
I have some questions related to my gls output, f you could help me please.

Are the values of P>z 0.000 normal? That means that they are significant at 1%?

Also can you please tell me anything about the Wald chi2(5) value and the z for income variable, because the income z is very high in comparison to the other variables?
