Bootstrap confidence intervals for adaptive cluster sampling design based on Horvitz-Thompson type estimators
Mohammadi, Mohammad; Salehi, Mohammad; Rao, J. N.K. ( 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 ... -
Complete allocation sampling: An efficient and easily implemented adaptive sampling design
Salehi, Mohammad; Brown, Jennifer A. ( 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, ... -
Inverse Adaptive Cluster Sampling with Unequal Selection Probabilities: Case Studies on Crab Holes and Arsenic Pollution
Salehi, Mohammad; Moradi, Mohammad; Al Khayat, Jassim A.; Brown, Jennifer; Yousif, Adil Eltayeb Mohamed ( Wiley Publishing Asia Pty Ltd. , 2015 , Article)Adaptive cluster sampling is an efficient method of estimating the parameters of rare and clustered populations. The method mimics how biologists would like to collect data in the field by targeting survey effort to localised ... -
Regression-type estimators for adaptive two-stage sequential sampling
Salehi, Mohammad; Panahbehagh, Bardia; Parvardeh, Afshin; Smith, David R.; Lei, Yuancai ( Springer , 2013 , Article)Adaptive two-stage sequential sampling (ATSSS) design was developed to observe more rare units and gain higher efficiency, in the sense of having a smaller variance estimator, than conventional sampling designs with equal ... -
Sampling of Multiple Variables Based on Partially Ordered Set Theory
Panahbehagh, Bardia; Bruggemann, Rainer; Salehi, Mohammad ( 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 ...
