Dear Statalisters
I am new to Stata and would appreciate your help with 2 questions.
1. I have an unbalanced panel and wish to create a variable that
identifies the presence of wave 1 respondents in subsequent waves in
order to test for attrition.
2. I wish to distribute the value of wave 1 dependent variables in the
unbalanced panel over subsequent waves.
Thanks in advanace.
Sara
