Asymptotic Probability Distribution of Sample Maximum

Extreme value theory is the most scientific approach to an inherently difficult problem - predicting the possibility that an extreme event will occur. Broadly speaking, there are two kinds of models for extreme values. The first group of models are models for a distribution of normalized maximum (minimum) of the sequence of independent identically distributed random variables. The second, more modern, group of models are the peaks-over-threshold (POT) models. These are models for all large observations which exceed a threshold. This paper is concentrated on the first type of model. Here, the maximum loss of a bank caused by different technological accidents and natural disasters is treated.
