Adaptive and unequal probability survey designs for environmental management
Brown, Jennifer A.; Salehi, Mohammad M.; Moradi, Mohammad; Panahbehagh, Bardia; Smith, David R. ( The Modelling and Simulation Society of Australia and New Zealand Inc , 2011 , Conference Paper)Designing an efficient large-area survey is a challenge, especially in environmental science when many populations are rare and clustered. Adaptive and unequal probability sampling designs are appealing when populations ... -
Adaptive two-stage inverse sampling design to estimate density, abundance, and occupancy of rare and clustered populations
Salehi, Mohammad; Smith, David R. ( Public Library of Science , 2021 , Article)Sampling rare and clustered populations is challenging because of the effort required to find rare units. Heuristically, a practitioner would prefer to discontinue sampling in areas where rare units of interest are apparently ... -
Asymptotic properties of the sample mean in adaptive stratified sequential sampling with multiple selection criteria
Parvardeh, Afshin; Panahbehagh, Bardia; Salehi M., Mohammad; Brown, Jennifer; Smith, David R. ( 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 ... -
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 ...
