Asymptotic properties of the sample mean in adaptive stratified sequential sampling with multiple selection criteria
(
Iranian Mathematical Society
, 2013 , Article)
We extend the method of adaptive two-stage sequen-tial sampling to include designs where there is more than one crite-ria used in deciding on the allocation of additional sampling effort. These criteria, or conditions, can ...
Sampling of Multiple Variables Based on Partially Ordered Set Theory
(
Iranian Statistical Society
, 2021 , Article)
We introduce a new method for ranked set sampling with multiple criteria. The method relaxes the restriction of selecting just one individual variable from each ranked set. Under the new method for ranking, units are ranked ...
An unbalanced ranked-set sampling method to get more than one sample from each set
(
American Association for Public Opinion Research
, 2018 , Article)
In ranked-set sampling, the restriction of selecting just one individual from each set may require too many sets. We propose a new version of ranked-set sampling that relaxes this restriction. Our new design uses stratified ...
Bootstrap confidence intervals for adaptive cluster sampling design based on Horvitz-Thompson type estimators
(
Kluwer Academic Publishers
, 2014 , Article)
Perez and Pontius (J Stat Comput Simul 76:755-764, 2006) introduced several bootstrap methods under adaptive cluster sampling using a Horvitz-Thompson type estimator. Using a simulation study, they showed that their proposed ...
Use of post-stratification in composite sampling for estimating mean
(
Springer
, 2011 , Article)
We show with the results of a study conducted in the Hamadan Province, Iran as to how the use of composite sampling for estimating mean zinc concentration in the soil can help reduce analytical costs by reducing the number ...
Complete allocation sampling: An efficient and easily implemented adaptive sampling design
(
Wiley
, 2010 , Article)
Adaptive sampling designs are becoming increasingly popular in environmental science, particularly for surveying rare and aggregated populations. An adaptive sample is one in which the survey design is modified, or adapted, ...
Horvitz-thompson estimator of population mean under inverse sampling designs
(
Iranian Mathematical Society
, 2012 , Article)
Inverse sampling design is generally considered to be an appropriate technique when the population is divided into two subpopulations, one of which contains only a few units. Here, we de- rive the Horvitz-Thompson estimator ...
Long-term COVID-19 booster effectiveness by infection history and clinical vulnerability and immune imprinting: a retrospective population-based cohort study
(
Elsevier
, 2023 , Article)
BackgroundLong-term effectiveness of COVID-19 mRNA boosters in populations with different previous infection histories and clinical vulnerability profiles is inadequately understood. We aimed to investigate the effectiveness ...
ESTIMATION OF THE LOCATION-SCALE PARAMETERS BASED ON RANKED SET SAMPLING COMBINED WITH ADDITIONAL BINOMIAL INFORMATION
(
ISOSS PUBLICATIONS
, 2023 , Article)
In this paper, we propose a modified version of ranked set sample which allows for the incorporation of more information in the inference procedure at almost no cost. This procedure is studied for the location-scale family ...
Confidence intervals for the two-parameter exponential reliability with type II censored data
(
Taylor and Francis Ltd.
, 2016 , Article)
We consider interval estimation of the reliability of the two-parameter exponential distribution.We consider asymptotic intervals, Bayesian, as well as intervals based on the generalized pivot variable. Transformations to ...
