Dear listers -
R 1.6, WINNT, S+2000 also
I am trying to implement a mark-recapture analysis in R. I have data on the
timing of the fledging of birds.
Over the course of a 35 day period, I have daily records of a) fledging, b)
alive or c) missing. e.g., on any given day, i can see a bird and know
that it has fledged (it has feathers now and wants to fly). Or I can see a
bird and it still has not fledged but is alive. Finally, I can not see the
bird on that day.
I am having trouble identifying what event code to give each of these
events in the interval censoring context
(0,1] - alive = ?
(0,1] - missing = ?
(0,1] - fledged = ?
any advice would be most appreciated.
