st: overall test of interaction

Dear list,
I am analysing my data using a stratyfied cox-regression analysis
Since I want to examine if any interaction occurs between education
and birthyear, I have inserted an interaction-term:
stcox i.education i.birthyear i.education#i.birthyear,
strata(group-id) vce(cluster person-id)
Is it possible for me to do an overall test in order to see, if the
interaction is significant? Since I am using vce(cluster), I cannot do
a lrtest of a model with and without the interaction term...
Best regards Grethe
