A Counterexample Concerning the External index
Abstract
The concept of an extremal index, which is a measure of local dependence amongst the exceedances over a high threshold by a stationary sequence, has a natural interpretation as the reciprocal of mean cluster size, A counterexample is exhibited which shows that this interpretation is not necessarily correct. Keywords: Poisson density function; Point processes; Stochastic processes.
