Actual probabilities of weediness in an operational setting were found to be much lower than would be expected based on the performance of the WRA against test data containing a high proportion of weeds, and uncertainty around classifications was high... The methods presented have wider application to the quantitative prediction of invasive species for situations where the base-rate probability of invasiveness is subject to uncertainty, and the accuracy of the screening test is imperfect... Statistical modelling was used to estimate the base proportion of introduced alien plants that will naturalise at some stage in the future, and determined the distribution of times until naturalisation for these plants...
