st: sensitivity and specificity after xtgee

Dear statalist members,
Is there any post-estimation option after running xtgee/ xtlogit (for
binary longitudinal regression) for calculating
sensitivity, specificity, positive and negative predictive values,
positive and negative likelihood ratios and ROC curve?
I used xtgee to fit binary regression for wheez syndrome with 3
measurements (baseline, first year and second year follow-ups) with
PD20 as exposure and broadcat and smoker_current as covariates:
xtset h_id h_int_no
xtgee wheez_symp pd_20_base i.broadcat smoker_current ,
corr(exchangeable) fam(binom) link(log/logit) eform robust
Regards,
Mohammadreza.
