Dear Robson, My apologize about my unclear question. I try to list the variables and data in rows rather than in colomn. File 1 Household(id1)-> 1, 1, 1, 2, 2, 2, 3, ... Child(id2)-> 2, 2, 3, 4, 3, 3, 5, ... Educlevel-> 2, 1, 1, 2, 2, 1, 1, ... X3(schooltype)-> a, b, a, b, a, a, b, ... X4(repetition) 2, 2, 2, 2, 2, 2, 2, ... Educlevel in strings. Educlevel=1 is primary school. Educlevel=2 is secondary level. A child may have secondary level and thus have records for his primary level along with other variables in file1. File 2 Household(id1)-> 1, 2, 3, ... Child(id2)-> 3, 1, 2, ... X3(ethnicity) 1, 3, 2, ... X4(livings)-> 1, 2, 2, ... In file 2 only single obs. I hope this is clearer. Thank you.
