Robust Design and Censoring

Postby cb » Tue Jun 04, 2019 10:15 pm

I have a robust design study where a few deaths (not many) have occurred during the secondary, closed period (and yes, I know that is not supposed to happen, but it is ecology after all). I received a suggestion to censor these records. I have two questions on this:

1. What exactly would censoring do in this context? My understanding is that censoring will result in the known detections being used for parameter estimation, while adjusting for mortalities. Is this correct?

2. How would I code this in RMark?

Thanks much!

This isn't a question about RMark even that it is posed as such. If censoring is done,it would have to be done in the analysis code which is MARK. RMark only does the model setup.

That said, the only censoring that I know of is loss on capture which is handled by assigning -1 to the value of freq. Not sure if that is allowed in the Robust design. Nor am I certain it will have the desired effect.
