Population estimation with performance guarantees
2007 IEEE International Symposium on Information Theory, 2007We estimate the population size by sampling uniformly from the population. Given an accuracy to which we need to estimate the population with a pre-specified confidence, we provide a simple stopping rule for the sampling process.

Cooperative estimation in heterogeneous populations
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011We consider the problem of cooperative distributed estimation within a network of heterogeneous agents. We begin with the situation where each agent observes an independent stream of Bernoulli random variables, and the goal is for each to determine its own Bernoulli parameter. However, the agents of the population can be categorized into a small number

Fine-grained population estimation
Proceedings of the 23rd SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2015We show how to estimate population numbers for arbitrary user-defined regions, down to the level of individual buildings. This is important for various applications like evacuation planning, facility placement, or traffic estimation. However, census data with precise population numbers is typically only available at the level of cities, villages, or ...

AbstractPopulation studies in archaeology rely on various methodological approaches, including the analysis of architectural remains, cemeteries, and field surveys. Chapter 3 of the book focuses on the different methods, formulae, and variables used to calculate population densities in both rural and urban areas.

Estimation of a Potential Hemodialysis Population
Medical Care, 1970Estimates have been made of the annual number of chronic hemodialysis candidates. Using mortality data and informed medical judgment, upper and lower bound estimates of the potential hemodialysis population were found to be from 6,700 to 8,400 annually for the age group 15-54 years.

Estimation of the Number of Classes in a Population
Biometrical Journal, 1988AbstractThe problem of estimating M, the number of classes in a population, is formulated as an occupancy problem in which N items are drawn from M urns. Under the assumption of a uniform distribution for the number of classes in the population, the sufficient statistic for M, which is the number of distinct classes observed, does not depend upon the ...

Estimating Past Population Trends
Annual Review of Anthropology, 1981A review of methods used to estimate past population trends and the theoretical models implicit in these methods is presented. The review is concerned both with efforts to estimate the size of a target population at a given moment in time and with efforts to examine population growth over time.

Sequential Estimation of the Size of a Population
Biometrika, 1972When estimating the size of a finite population, it is possible to consider, as an alternative to the capture-recapture method, a sequential scheme. Suppose an urn contains an unknown number, N, balls, initially all white. A single ball is drawn at random and if it is white it is painted black and returned to the urn, while if it is black, indicating ...
