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
