Abstract

Sampling design and experimental design have developed relatively independently in recent statistical history. However, many studies do involve both a sampling design and an ex-perimental design. For example, a polluted site may be exhaustively partitioned into area plots, a random sample of plots selected, and the selected plots randomly assigned to three clean-up regimens. To date there is no commonly used procedure for incorporating both the sampling design and the experimental design into the estimation of treatment effects. For this reason we will consider an estimator of treatment effect that does incorporate both sampling and experimental designs and discuss some of it's properties.

AN ESTIMATOR OF TREATMENT EFFECTS UNDER COMBINED SAMPLING AND EXPERIMENTAL DESIGNS

Sampling design and experimental design have developed relatively independently in recent statistical history. However, many studies do involve both a sampling design and an ex-perimental design. For example, a polluted site may be exhaustively partitioned into area plots, a random sample of plots selected, and the selected plots randomly assigned to three clean-up regimens. To date there is no commonly used procedure for incorporating both the sampling design and the experimental design into the estimation of treatment effects. For this reason we will consider an estimator of treatment effect that does incorporate both sampling and experimental designs and discuss some of it's properties.
