Hi
I'm running a probit model like:
probit enrol x1 x2 [pweight=weight], cluster(prov)
I understand why I should use the cluster option but I'm really struggling with understanding what's happening more formally.
I would like to write the log likelihood function. However; I do not understand how to incorporate the clusters.
Will the clusters influence the likelihood function?
I guess my question is stupid but I'm really struggling with this and would really appreciate any help I could get.
Best regards
