Efficient Semi-Latin Rectangles: Designs for Plant Disease Experiments

Experiments on disease in plants often use half-leaves as experimental units. The whole leaves are typically in the rectangular array formed by h leaf-heights (rows) and p plants (columns), where h < p . We specialize to the case where h = n and p = 2 n and there are 2 n treatments. If each treatment occurs once per column and twice per row, we call such a design a semi-Latin rectangle. Efficient semi-Latin rectangles of such sizes are constructed for 2 ≤ n ≤ 10. Guidance is given on their use.

Soccer matches as experiments: how often does the ‘best’ team win?

Models in which the number of goals scored by a team in a soccer match follow a Poisson distribution, or a closely related one, have been widely discussed. We here consider a soccer match as an experiment to assess which of two teams is superior and examine the probability that the outcome of the experiment (match) truly represents the relative abilities of the two teams. Given a final score, it is possible by using a Bayesian approach to quantify the probability that it was or was not the case that ‘the best team won’. For typical scores, the probability of a misleading result is significant. Modifying the rules of the game to increase the typical number of goals scored would improve the situation, but a level of confidence that would normally be regarded as satisfactory could not be obtained unless the character of the game was radically changed.
