keywords: Capture-recapture, tag-loss, overestimation, drug addicts
In capture-recapture experiments, if individuals lost their tags, the observed recaptures will be smaller than expected. This phenomenon results in overestimation of the population under consideration. Drugs addicts are usually referred for treatment or/and rehabilitation, on the process of these, they are likely to change their identity hence losing their tags. Tags loss method was therefore incorporated in the estimation of the size of elusive population. The simulation studies revealed that the proposed coverage probability tag loss model (CPTLM) is statistically consistent with small and large population sizes. The proposed model was applied to addicts’ data collected from Northeast, Nigeria.
