Hello everyone,

I am currently working on LSMS-ISA for Nigeria, however, whilst some sections have unique identifiers as "indiv", that is the individual id, some have "hhid" as the unique identifier, some "item_cd", the id for items and one of the sections on enterprise is uniquely identified by "ent_id". I want to use household as the unit of analysis and also to merge the different sections but I don't know how to go about doing these.

Thank you all in advance.
