Re: [datatable-help] Correcting for transience in mark-recapture data with R

Hi everyone, Small update: I think the (main) problem is with estimation of M (= total # of marked individuals). By definition, M in year /t/ should always be equal or greater than the M in year /t-1/, and for the final year M should be /total number of rows in the dataset/, right? However, the

Hi everyone, I'm working on estimating the population size of Risso's dolphins in the Azores using mark-recapture data, whereby I take transient individuals into account (i.e., I estimate a transience-corrected population size). For this, I use an R script, as used in Madon et al (2013) (see link
