Modelling of precipitation extremes using parametric and nonparametric methods with automated threshold selection

When dealing with extreme values estimation, the threshold models are often used. However, a~proper threshold selection is one of the problems which have to be solved. In this paper, we concentrate on this issue in order to compare an~automated threshold selection based on multiple-threshold model with double bootstrap technique based on semi-parametric estimation. Both estimation procedures are compared using simulations. A~case study is carried out to evaluate estimations of intensity-duration-frequency curves which represent commonly used hydrological tool. A~special attention is also paid to the assessment of an~impact of the series length on the estimation quality.
