Fig. 2.

Representation of the 7 biosecurity hazards (red) on a plane defined by the two main dimensions identified using Multiple Correspondence Analysis. The axis values are the square of the correlation coefficients between the hazard and the dimension and hence are a measure of the quality of the projection of the hazard on the dimension. Hence, ‘Forklift’ is strongly related to dimension 1 and ‘Between sheds’ with dimension 2. Among the supplementary variables (blue indicates categorical variables and green continuous variables), total biosecurity score (‘total’) is strongly explained by dimensions 1 and training (‘No training’) less so, while ‘company’ is not influenced by either dimension. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
