Field experimentation on rough land: The method of Papadakis reconsidered

The Journal of Agricultural Science, 1998
Journal of Agricultural Science, Cambridge (1998), 131, 1After the publication of this paper a fault was found in the software used to calculate the tables, the numbers of rows and columns having at one point been interchanged. Although that will not affect results from the square formats α and β, it could affect those from γ.

Role of the Papadakis Estimator in One- and Two-Dimensional Field Trials

Biometrika, 1985
Abstract : Field trials when observations are correlated with those in neighboring or nearby plots in one and two dimensions are analyzed using simultaneous autoregressive models. The relationships between the maximum likelihood solutions and the corresponding well-known Papadakis estimators are clarified and it is shown that the maximum likelihood ...

A simulation study of the nearest neighbour analysis method of papadakis

Communications in Statistics - Simulation and Computation, 1985
The relative performances of randomised block, balanced lattice squares and Papadakis nearest neighbour analyses were compared on two simulated fields whose soil heterogeneity profiles were generated, one with a few evenly spaced contours and the other with many unevenly spaced contours.

How well is the United States competing? A comment on Papadakis

Journal of Policy Analysis and Management, 1996
We contend that Papadakis's inferences regarding past and future competitiveness crises cannot be made on the basis of the evidence she has presented. We support this assertion in three ways. First, we argue that the import penetration ratio is not a reasonable measure of national competitiveness in international markets.

On the unbiasedness of the Papadakis estimator and other nonlinear estimators of treatment contrasts in field-plot experiments

Biometrika, 1989
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.

Determination of the main agricultural crops for the Metropolitan Puebla-Tlaxcala area using the Papadakis Methodology

Agro Productividad
agricultural crops in the Puebla-Tlaxcala Metropolitan Area (ZMPT). Design/methodology/approach: From April to June 2022, the classification process for identifying the main crops in the ZMPT was conducted. This process utilized monthly climatic data from the Mexican Institute of Water Technology (IMTA), analyzed through the Papadakis methodology (1970)
