I have a problem of quasi-complete separation in my logit model for
[ropensity score matching. I tried using firthlogit instead and I get
the following error "initial vector: matrix must be dimension 27".

In PSM is it worthwile to correct for separation if it occurs? Since I
am unable to solve this problem, should instead remove the problematic

Kindly advise
