Find out why hydrometeorological hazard events are not independent and what this means for estimates of annual losses, reinstatement premiums etc.

Among other things, Prof Stephenson ascertains that the dependency between events is an inevitable consequence of event probabilities depending on time-varying background factors. He also explains how generalised linear and other statistical regression models can be used to investigate and quantify the dependencies e.g. clustering of European windstorms.
