Optimisation of the T-square sampling method to estimate population sizes. [PDF]

open access: yes, 2007
Population size and density estimates are needed to plan resource requirements and plan health related interventions. Sampling frames are not always available necessitating surveys using non-standard household sampling methods.

UC1 sampling plan, liquid waste storage tanks, JRC Ispra

open access: yesEPJ Nuclear Sciences & Technologies, 2020
The objective of INSIDER work package 3 (WP 3) is to draft a sampling guide for initial nuclear site characterization in constrained environments, based on a statistical approach.

Towards the Development of a More Accurate Monitoring Procedure for Invertebrate Populations, in the Presence of an Unknown Spatial Pattern of Population Distribution in the Field

open access: yesInsects, 2018
Studies addressing many ecological problems require accurate evaluation of the total population size. In this paper, we revisit a sampling procedure used for the evaluation of the abundance of an invertebrate population from assessment data collected on ...

Short-Run Contexts and Imperfect Testing for Continuous Sampling Plans

open access: yesAlgorithms, 2018
Continuous sampling plans are used to ensure a high level of quality for items produced in long-run contexts. The basic idea of these plans is to alternate between 100% inspection and a reduced rate of inspection frequency.

Design of Multiple Dependent State Sampling Plan Application for COVID-19 Data Using Exponentiated Weibull Distribution

open access: yesComplexity, 2021
The proposed sampling plan in this article is referred to as multiple dependent state (MDS) sampling plans, for rejecting a lot based on properties of the current and preceding lot sampled. The median life of the product for the proposed sampling plan is

Sampling plan

open access: yesComputers & Mathematics with Applications, 1988
Poisson distribution is usually used as an approximation of a binomial distribution to construct sampling plans and control charts. This is quite appropriate as the Poisson probability distribution gives good approximation of the more exact but more tedious binomial distribution.

A representative sampling plan for auditing health insurance claims

open access: yes, 2007
A stratified sampling plan to audit health insurance claims is offered. The stratification is by dollar amount of the claim. The plan is representative in the sense that with high probability for each stratum, the difference in the average dollar amount ...

Comparison of Skip-lot sampling plans (SkSP-V vs. SkSP-2) [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2014
The purpose of Skip-lot sampling is to reduce the Average Sample Number (ASN) and Average Total Inspection (ATI) as well as inspection costs. The Skip-lot concept is economically advantageous to make decision on the submitted lot.

Comment on Article by Ferreira and Gamerman [PDF]

open access: yes, 2015
A utility-function approach to optimal spatial sampling design is a powerful way to quantify what "optimality" means. The emphasis then should be to capture all possible contributions to utility, including scientific impact and the cost of sampling.
