Dear Statalisters,
I have an annual study where people report their status (employed /
unemployed). It is not always asked when the transition from one state
to another had happened. What can I do to smartly (hm...) assign
the initiating and terminating times? A simple thing to do is to
take the middle of the interval as the time of change. A better thing
might be to integrate out the missingness in the style of EM algorithm.
Can anybody provide a reference to what can be / should be / sometimes
is done?
