Partially Replicated Latin Squares

Youden, W. J., Hunter, J. S.·1955·Biometrics

Abstract

Latin squares have been used for over 30 years in agricultural field trials (1). Often the double restriction imposed by the row and column arrangement brought a welcome reduction in the mean square for error. The row and column mean squares were of no interest. Eventually the Latin square arrangement found application where the rows and columns corresponded to clearly defined physical entities. Youden (3) in studies on tobacco mosaic virus observed that the number of lesions produced on leaves depended upon the position of the leaf on the plant and that plants also differed markedly in susceptibility to lesions. Furthermore, for a given lot of plants, the effect of leaf position was closely the same from one plant to another. Very large reductions in the error mean square resulted from the use of a Latin square. The plants were columns and leaf positions were rows. Here there was some interest in the mean squares for rows and columns though the chief concern was with the treatments applied to the leaves. Later Yates (2) introduced confounding into Latin square designs. Probably it was inevitable that the Latin square arrangement would be tried when the rows and columns were used for factors that not only were likely to interact with the treatments (letters) but also with each other. The form or appearance of a Latin square remains but the substance is lost. The fractional replication of a factorial experiment that results from this practice is a particularly unfortunate one…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
