Abstract/Description:
We propose a ratio estimator to determine population estimates using capture-recapture sampling. It's different than traditional approaches in the following ways:(1)Ordering of recaptures: Currently data sets do not take into account the "ordering" of the recaptures, although this crucial information is available to them at no cost. (2)Dependence of trials and cluster sampling: Our model explicitly considers trials to be dependent and improves existing literature which assumes independence. (3)Rate of convergence: The percentage sampled has an inverse relationship with population size, for a chosen degree of accuracy. (4)Asymptotic Attainment of Minimum Variance (Open Systems: (=population variance).(5)Full use of data and model applicability (6)Non-parametric (7)Heterogeneity: When units being sampled are hard to identify. (8)Open and closed systems: Simpler results are presented separately for closed systems.(9)Robustness to assumptions in open systems
