On the prediction of means in a finite population

Statistics & Probability Letters, 1986
Consider a general superpopulation model with \[ Y_ t=g(X_ t;d_ 0)+e_ t \] where \(E(e_ t| X_ t)=0\), \(V(e_ t| X_ t)=\sigma^ 2a_{tt}\) and \(Cov(e_ t,e_ s| X_ t,X_ s)=0\) and g has a known parametric form and is continuous. When a consistent estimator of \(d_ 0\), say \(\hat d_ 0\) is obtained, consider the predictor \[ \bar y_ A=N^{-1}n\bar y_ n+(1-N^

Estimation of the mean of the selected population

Communications in Statistics - Theory and Methods, 1988
A new class of estimators is introduced for the problem of estimating the mean of the selected population. These estimators are found by subtracting from the largest sample mean an estimator of its bias. The new estimators are compared with those introduced by Cohen and Sackrowitz (1982) and in terms of frequentist risk they are found to perform quite ...

Estimation of the Mean of the Selected Population

Journal of the American Statistical Association, 1974
Abstract Let X i1, X i2, …,X in, i = 1, 2, be a pair of independent random samples from normal populations with means θi , and common known variance τ2. Suppose we select the population which provides the larger sample mean. In this article our main aim is to investigate different estimators for the mean of the selected population.
