Summary One problem in statistics is to determine the distributions of estimators and statistics. For distributions of the continuous type the density function of an estimator can at each point be expressed as a multiple integral, but the standard methods for computing integrals are not...

Summary The occurrence of scientific fraud damages the credibility of science. An instrument to discover deceit was proposed with Benford’s law, a distribution which describes the probability of significant digits in many empirical observations. If Benford-distributed digits are expected and...

Summary Several nonlinear time series models have been proposed in the literature to explain various empirical nonlinear features of many observed financial and economic time series. One model that has gained much attention is the so-called self-exciting threshold autoregressive (SETAR) model....

Summary This paper examines the predictive power of different estimation approaches for reservation wages. It applies stochastic frontier models for employed persons and the approach from Kiefer and Neumann (1979b) for unemployed persons. Furthermore, the question of whether or not reservation...

Deterministische Discounted Cash Flow Modelle (DCF-Modelle) greifen im Rahmen der Unternehmensbewertung lediglich auf einwertige Größen zurück. Bei stochastischen Modellen werden einzelne Plangrößen hingegen mehrwertig dargestellt, indem aus Wahrscheinlichkeitsverteilungen verschiedene...
