Re: st: test of coefficients of the same regression equation

[Florian Wendelspiess Chávez Juárez <florian@chavezjuarez.com>]

Hi Nahla

I think you can simply use:
test [mean]NSP = [mean]Times_2

    or even

test NSP = Times_2
in this case, since there is only one equation as I see.

I hope this help.
Best regards,
Florian
