Unbiasedness of the Papadakis Estimator and Other Nonlinear Estimators of Treatment Contrasts in Field-Plot Experiments.

摘要

Spatial methods for the analysis of field-plot experiments are considered. Estimators of treatment contrasts obtained by these methods are generally complicated nonlinear functions of the observations. Sufficient conditions for these estimators to be unbiased under a postulated true model are obtained.
