No, xb is just the fitted values.
You can obtain the predicted individual effects using -gllamm-.
A similar question was asked in April. Sophia Rabe-Hesketh

replied:
"If your xtprobit command was
xtprobit y x1 x2, i(id) re,
you can estimate the model in gllamm using
gllamm y x1 x2, i(id) link(probit) fam(binom) adapt
Then use
predict res, u
to get empirical Bayes predictions of the random
effects. The posterior means will be stored in
resm1 and the posterior standard deviations in
ress1.
The latest version of gllamm is available from SSC,

Hope this helps,
Scott
