A Relationship between Efficiencies of Marginal Designs and the Product Design.
A simplified treatment of the restricted analysis of a slightly disproportionate factorial experiment.
This paper considers a procedure to obtain effect estimators in the least squares analysis of a slightly disproportionate factorial design when a sample survey is made of the results of an extensive experiment. Explicit formulae have been found for the restricted estimators and their variances, when the constraints normally imposed upon a proportional model are used. In addition, an approximate analysis of the original model is used to perform that estimation, and an approximate analysis of variance...

Análisis de diseños factoriales sin replicación.
En este artículo se propone un método para identificar efectos significativos en diseños factoriales sin replicación, resolviendo el problema como un caso de determinación de observaciones atípicas (outliers) en muestras altamente contaminadas. Para ello se deriva un estimador robusto de escala basándose en simulaciones realizadas con ordenador. El método es extremadamente sencillo de aplicar y conduce a los mismos resultados que el proyectado por Box y Meyer (1986) que es de mayor complejidad.
