Distance sampling is a widely used method to estimate animal population size. Most distance sampling models utilize a monotonically decreasing detection function such as a half-normal. Recent advances in distance sampling modeling allow for the incorporation of covariates into the distance model, and the elimination of the assumption of perfect detection at some fixed distance (usually the tran...

A large health survey was combined with a simulation study to contrast the reduction in bias achieved by double sampling versus two weighting methods based on propensity scores. The survey used a census of one New York county and double sampling in six others. Propensity scores were modeled as a logistic function of demographic variables and were used in conjunction with a random uniform variat...

Population proportion is the percentage of the population that has a particular characteristic. The estimation for population proportion has broad applications in academic and industry fields such as insurance, banking, medical studies, bio-complexity and so on. Regarding an estimation procedure for population proportion, sampling scheme plays an important role. It directly decides the sampling...

In this paper, we develop double acceptance sampling plan and group acceptance sampling plan for an inverse Weibull distribution based on a truncated life test. We consider the median lifetime of the test units as a quality parameter and obtain the design parameters such as sample size and acceptance number. These plans are obtained under the consumer’s risk and the producer’s risk simultaneous...

Transformation techniques have been used to increase the efficiency of estimators in sample surveys. In this paper, some classes population mean using transformation on an auxiliary variable and both study variables proposed under double sampling. We obtain biases square errors up first order approximation. A simulation application a rubber production dataset illustrate performance estimators. ...
