• Finite population small area interval estimation 

      Zhang, Li-Chun (Journal article; Peer reviewed, 2007)
      Small area intervall estimation is considered for a finite population, where the small area parameters are treated as fixed constants. Design based direct estimation yealds intervals that are too long to be useful. Model ...
    • A note on post-stratification when analyzing binary survey data subject to nonresponse 

      Zhang, Li-Chun (Journal article; Peer reviewed, 1999)
      In this article we presents some results regarding the effect of post-stratification when analyzing binary survey data to nonresponse. Assuming that nonresponse depends on the variable of interest which is missing for ...
    • A note on the effect of auxiliary information on the variance of cluster sampling 

      Hagesæther, Nina; Zhang, Li-Chun (Journal article; Peer reviewed, 2009)
      A model-based synthesis is presented for a number of well-known results concerning the design effect of cluster sampling. This helps to yield a simpler perspective, making the design-based expressions more transparent. ...
    • On some common practices of systematic sampling 

      Zhang, Li-Chun (Journal article; Peer reviewed, 2008)
      Systematic sampling is widely used technique in survey sampling. It is easy to execute, whether the units are to be selected with equal probability or with probabilities proportional to auxiliary sizes. It can be very ...
    • Simultaneous estimation of the mean of a binary variable from a large number of small areas 

      Zhang, Li-Chun (Journal article; Peer reviewed, 2003)
      We develop a frequentist method of simultaneous small area estimation under hierarchical models. The simultaneous estimator is the best ensemble predictor under the model. It is preferable to the area-specific best predictor ...
