Abstract:

In enviromental statistics, there is often the need to predict extreme values of given features (such as heat, rainfall, and pollution). When extreme values lead to emergencies, quick updating of predictions is necessary, too. We shall first assume that the underlying process is normal and then relax this assumption by considering the more general skew-normal process. The method is applied to real enviromental data.
