Thanks to Bryan Sayer for his reply.
We are not sure of the format since the example we can see in the Stata manuals (version 6.0) is using dummy variables to indicate the explanatory variables. Our output is as follows
. xi:svyologit hivchance i.gender i.v130
i.gender _Igender_1-2 (naturally coded; _Igender_1 omitted)
i.v130 _Iv130_1-6 (naturally coded; _Iv130_1 omitted)
Survey ordered logistic regression
pweight: v005 Number of obs = 7479
Strata: v022 Number of strata = 84
PSU: v001 Number of PSUs = 176
Population size = 7.406e+09
F( 5, 88) = 12.74
Prob > F = 0.0000

We wish to use svytest to test the significance of the explanatory variable "v130" - we are not sure how to specify that.
Many thanks for your help in advance,

The test for each coefficient is just the t-test in the output. Use -svylc-
and -svytest- to test linear combinations of coefficients.

Subject: st: Command format svytest
Dear colleagues,
I am sorry for what maybe a trivial question. Would anyone know the format
for running an "svytest" post a "svyologit" command as such
xi: svyologit hivchance i.gender i.region i.educg i.marstatus
We wish to perform individual hypotheses testing of each explanatory
variable to asses the goodness-of-fit (since svyologit is estimated using
pseudo-likelihood).
Many thanks for your help in advance.
