Choosing Model

Postby alipichun » Wed Jun 27, 2018 1:25 pm

My study is based on data from marked gannets and re-sighting each year. Following the book the chapter for the model mark-resighting says that this model analyzes marked individuals and also unmarked individuals. In my case I am only analyzing tagged individuals presence or absence every year, and not looking at unmarked ones. Should I still use this model or should I better change to mark-recapture?

Mark-recapture, in the broad sense. What flavour of model(s) you use depends on the data you have -- live encounter only, live encounter + dead recovery, and so on.
