I'm not sure if I get your question right, but I want all contracts who are not disjoint concerning id's to have the same household_id.
If I use
egen group = group(contract)
on my data, the result is
contract | id | group
___________________________
123 | 1 | 1 <-
123 | 2 | 1
123 | 3 | 1
456 | 4 | 2
456 | 5 | 2
678 | 1 | 3 <-
And as groups "1" and "3" are not disjoint concerning id's, I would like to have them the same household_id, like this:
contract | id | household_id
___________________________
123 | 1 | 1 <-
123 | 2 | 1
123 | 3 | 1
456 | 4 | 2
456 | 5 | 2
678 | 1 | 1 <-
