Qqvalue: q-values the same as p-values

[Elizabeth Thompson]

Hello,

I am using Stata 15.1. I ran a GLM in svy, and then used parmest to generate an output dataset with a p-value variable (I installed the Stata 11 version, as the latest parmest program is for Stata 16.0). I then used qqvalue to obtain p-values adjusted for multiple comparisons using the Simes method. However, my q-value for my independent variable (lgb) is equal to its p-value. I've ran multiple GLMs, both adjusted and unadjusted, on different outcome variables and I keep having the same issue. Does anyone have an idea why this might happen?

Here is my code and output:

svy: glm q1_bin2 i.lgb pscore, family(binomial) link(identity)
parmest, list(,)saving("C:\filepath")
use "C:\filepath"
qqvalue p, method(simes) qvalue(simes)
