predictions is summarised by maps showing the ratio of the inter-quartile
range (IQR) to its mean (
Fig. 1.4
A1-D1). The IQR is a simple measure of
the precision with which each value is predicted, and standardisation by the
mean produces an uncertainty index less affected by underlying prevalence
levels and more illustrative of relative model performance. This index was
then also weighted by the underlying population density to produce a sec-
ond map indicative of those areas, where uncertainty is likely to be most
operationally important (
