Es ist mittlerweile weitgehend unbestritten, dass der demographische Wandel eine grundlegende Reform der gesetzlichen Rentenversicherung erforderlich macht. Dies soll im Wesentlichen durch die Einführung einer Zusatzrente auf Kapitalbasis (Teilkapitaldeckungsverfahren) erfolgen. Der Beitrag...

Jaynes (1957a,b) formulates the maximum entropy (ME) principle as the search for a distribution maximizing a given entropy under some given constraints. Kapur (1984) and Kesavan & Kapur (1989) introduce the generalized maximum entropy principle as the derivation of an entropy for which a given...

Sample size analysis is a key part of the planning phase of any research. So far, however, limited literature focusses on sample size analysis methods for two-sample linear rank tests, although these methods have optimal properties at different distributions. This paper provides a new sample...

J.M. Keynes (1911) shows how distributions look like for which the arithmetic, the geometric and the harmonic mean are most probable values. We propose a general class of distributions for which the quasi-arithmetic means are ML-estimators such that these distributions can be transformed into an...
