Wald test from GLM estimation

[Stephen Okiya]

Hi,
I am using Stata 18 and am performing a GLM estimation using survey design effects and would be interested in the p-value of a Wald test of co-efficients. The idea is to have something in line of an ANOVA but through GLM.
My example data is

end
label values popgroup_r popgroup_r
label def popgroup_r 1 "A", modify
label def popgroup_r 2 "B", modify
label def popgroup_r 3 "C", modify

and the code am using is

svy: glm  inc_01 i.popgroup_r, family(gaussian) link(identity) ml

Thanks in advance!
