Calculating Nest Survival with known failure dates

[hjh_22]

Hi,
I'm trying work out how to do a nest survival analysis in MARK (or RMark) using artificial nests monitored by camera traps, along with several covariates (all factors). However, I originally overlooked the fact that the standard MARK nest survival analysis doesn't work when you use the exact known failure (predation) day for last day present and last day present. ie I can't get it to work because my data is too precise and clearly I don't want to lose that precision by adding in fate uncertainty as that would defeat the point of knowing the exact predation timing and id.
Is there an alternative approach I should consider within MARK or should I go back to R?

Any thoughts or suggestions welcome.
thanks, Hugh

It sounds to me like you have known fate data (p=1). You could use either model="Known" or use the vast amount of software for std survival analysis. The latter would be better if you have lots of occasions or want to use continuous time. The focus of MARK is discrete sampling and p<1 but it does have the known fate model.
