    • 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 ...
