| Zusammenfassung |
| In this communication, I improve the detection and modeling of the
over-dispersion of winter storm occurrence. For this purpose, the
generalized Poisson distribution and the Bayesian information criterion are
introduced; the latter is used for statistical model selection. Moreover, I
replace the frequently used dispersion statistics by an over-dispersion
parameter which does not depend on the considered return period of storm
events. These models and methods are applied in order to properly detect the
over-dispersion in winter storm data for Germany, carrying out a joint
estimation of the distribution models for different samples. |
