Effective/census population size ratio estimation: a compendium and appraisal
With an ecological-evolutionary perspective increasingly applied toward the conservation and management of endangered or exploited species, the genetic estimation of effective population size (N(e)) has proliferated. Based on a comprehensive analysis of empirical literature from the past two decades, we asked: (i) how often do studies link N(e) to the adult census population size (N)? (ii) To w...
متن کاملA finite-population revenue management model and a risk-ratio procedure for the joint estimation of population size and parameters
Many dynamic revenue management models divide the sale period into a finite number of periods T and assume, invoking a fine-enough grid of time, that each period sees at most one booking request. These Poisson-type assumptions restrict the variability of the demand in the model, but researchers and practitioners were willing to overlook this for the benefit of tractability of the models. In thi...
متن کاملEfficient and Unbiased Estimation of Population Size
Population sizing from still aerial pictures is of wide applicability in ecological and social sciences. The problem is long standing because current automatic detection and counting algorithms are known to fail in most cases, and exhaustive manual counting is tedious, slow, difficult to verify and unfeasible for large populations. An alternative is to multiply population density with some refe...
متن کاملPopulation size estimation and Internet link structure
Traceroute sampling is a common approach for exploring the autonomous system (AS) graph of the Internet. It provides samples of links between autonomous systems, but these links are not drawn uniformly at random from all possible links. Rather, the rules that each AS uses are idiosyncratic and emergent. Here, we are interested in using the data from traceroute sampling to estimate the degree di...
متن کاملEstimation of a Ratio in the Finite Population
Estimation of the ratio of two totals is considered, when a probability sample from the finite population is available. Four estimators of the ratio are examined. The first one – called “simple” – is the ratio of the Horvitz–Thompson estimators of totals; the second – the ratio of two ratio estimators of totals; the third one – the ratio of two regression estimators of totals. The fourth one is...
