Each group of variables was then evaluated by PCA to identify principal components (PCs) that accounted for a small amount of variance and to eliminate variables using minimum principal components (following Hawkins and Fatti 1984 ). With a successive series of PCA and inspection of the biplot display, three variables were detected, viz. e. t(y 0 )) for the time in days from transplanting in the field until the first symptoms. These variables were retained to provide an overall description of the epidemics, accounting for 83% of the variance of the original variables.

1) and classification (Sect. 3) introduced by epidemiologists in a number of chapters in Kranz (1990a) and summarised by Campbell (1998). An outline on statistical equivalence (Sect. 2) is added. The choice of a statistical technique for comparative epidemiology with their respective test parameters already has to be considered when a research project is planned depending on its objective and the type of data expected. 2. 1 Methods for Statistical Ordination Most methods of statistical ordination (Hau and Kranz 1990) can also be useful for studies across pathosystems when appropriately employed.

Randomised block design), under controlled experimental conditions or by means of computer simulation. Among the posterior analyses Blettner et al. (1997) distinguish four types: (I) classical reviews as qualitative summaries, (2) quantitative summaries, (3) metaanalyses as a new evaluation across available studies and data sets (Sect. 3), and (4) prospective planning for pooled evaluation. Strictly speaking, type (4) is not a posterior analysis (Blettner et al. 1997), but a coordinated research project, organised either as a loose network or as a consortium.
