I describe an open-source R package, multimark, for estimation of survival and abundance from capture-mark-recapture data consisting of multiple "noninvasive" marks. Noninvasive marks include natural pelt or skin patterns, scars, and genetic markers that enable individual identification in lieu of physical capture. multimark provides a means for combining and jointly analyzing encounter histori...

We propose a novel approach for modeling capture-recapture (CR) data on open populations that exhibit temporary emigration, while also accounting individual heterogeneity to allow differences in visit patterns and capture probabilities between individuals. Our combines changepoint processes—fitted using an adaptive approach—for inferring visits, with Bayesian mixture modeling—fitted nonparametr...

Recapturing and rebroadcasting of images are common attack methods in insurance frauds face identification spoofing, an increasing number detection techniques were introduced to handle this problem. However, most them ignored the domain generalization scenario scale variances, with inferior performance on shift situations, normally exacerbated by intra-domain inter-domain variances. In paper, w...

Capture-recapture methods, largely developed in ecology, are now commonly used in epidemiology to adjust for incomplete registries and to estimate the size of difficult-to-reach populations such as problem drug users. Overlapping lists of individuals in the target population, taken from administrative data sources, are considered analogous to overlapping "captures" of animals. Log-linear models...

1. There may be bias associated with mark–recapture experiments used to estimate age and growth of freshwater mussels. Using subsets of a mark–recapture dataset for Quadrula pustulosa, I examined how age and growth parameter estimates are affected by (i) the range and skew of the data and (ii) growth reduction due to handling. I compared predictions from von Bertalanffy growth models based on m...
