Hi,

I am running the following regression

areg fullschool i.female i.eldstchild i.birthorder i.age
i.female#i.eldstchild,absorb (hhid) vce(cluster hhid)

and i get the following warning

Warning:  variance matrix is nonsymmetric or highly singular

I am unsure as to what could be causing this.

Any ideas?

Thanks

Urmi
