Similarly, data from the
South American sites were used to predict daily severity at
each of the Australian sites. These are referred to as the
‘continent-wise models’. Second, data for all sites were
pooled together and ANN and REG models were developed
using data for six Australian and South American
sites to predict the severity class for the remaining seventh
site. This way each site was dropped in turn and the daily
severity class of the dropped site was predicted using models
developed from the six remaining sites.
