PROs & CONs
Pareto alpha estimation
Maximum FRP Fires above 600mW
+ proven statistical model
+ the potential for ultra large fires can be displayed
+ the frequency of large events is accounted for
- threshold selection & fit are critical
- the frequency of large fire events is neglected
- empirical threshold selection- peak events are neglected
