      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 ...
    • Horvitz-thompson estimator of population mean under inverse sampling designs 

      Mohammadi, Mohammad; M, Mohammad Salehi ( 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 ...
