Let {Xn} be a stationary sequence with marginal distribution in the domain of attraction of a max-semistable distribution. This includes all distributions in the domain of attraction of any max-stable distribution and also other distributions like some integervalued distributions with exponential type tails such as the Negative Binomial case. We consider(More)
