Cluster standard errors

[Shailaja Tiwari]

Is there a way to manually cluster standard errors?

I am using the user written command

selmlog13 which estimates linear regression models on a selected subset of observations, where selectivity is modelled as a multinomial logit.

the selmlog13 command however allows me to bootstrap the standard errors not to cluster them.
I am wondering if it is possible for me to cluster my standard errors manually?

whenever Stata does not allow something, there are sound methogological reasons.
