    • 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 ...

    • 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 ...

    • 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 ...
