Hi,
I have a question that I hope somebody can help me with. I want to
transform a single record into multiple records to analyze individual
episodes with an spell specific id.
Specifically I have panel data with the following form with year
denoting year-quarter
id year x
1 20001 1
1 20043 0
2 19973 1
3 20011 1
4 19974 0
4 20032 1
The year variable denotes when an event occurred for the specific
unit. I want to transform this data into
the following format (data starts in 19971 and assuming that only have
non-left censored data):
id episode begin end x
1 1 19971 20001 9 (unknown)
1 2 20002 20043 1
1 3 20044 . (censored) 0
2 1 19971 19973 9
2 2 19974 . 1
3 1 19971 20011 9
3 2 20012 . 1
4 1 19971 19974 9
4 2 19981 20032 0
4 3 20033 . 1
Could someone help me out with this? Thanks.
Regards,
Marcus
