how can i replace a regresion statistic with the statistic of another regression?

[Allan Andreotti]

Hi, for exmaple i hav this regresion
reg y x
outreg2 using myfile

But i want to report the F statistic from another regresion

reg x z w
test z w

Thank you.

outreg2 is from SSC. You want

test z w
local F= r(F)
reg y x
outreg2 using myfile, addstat("Wald statistic", `F')
