Diese Arbeit beschäftigt sich mit speziellen Aspekten der stochastischen Überlagerung, die als Anonymisierungsmethode zur Sicherstellung der faktischen Anonymität von Mikrodaten eingesetzt wird.2 Insbesondere soll der Zusammenhang zwischen der Überlagerung mittels einer Mischungsverteilung...

This article sets out a simple formula for theoretical evaluation of the normal distribution function (F(z)) with greatest absolute error less than 5times;10^-8. The proposed formula is based on values of z agrave;454 (-acirc;21E,+acirc;21E) and is generated by applying polar integral,...

Econometric Modeling provides a new and stimulating introduction to econometrics, focusing on modeling. The key issue confronting empirical economics is to establish sustainable relationships that are both supported by data and interpretable from economic theory. The unified likelihood-based...

This paper studies aspects of the broad class of log-concave probability distributions that arise in the economics of uncertainty and information. Useful properties of univariate log-concave distributions are proven without imposing differentiability of density functions. We also discuss...

In this paper we propose a mixture model of willingness to pay distributions for contingent valuation studies. By allowing a point mass at zero, this model nests the conventional model as a special case. We discuss both parametric and nonparametric estimations of the mixture model. We consider...

In certain cases partial sums of i.i.d. random variables with finite variance are better approximated by asequence of stable distributions with indices alpha n - 2 than by a normal distribution. We discusswhen this happens and how much the convergence rate can be improved by using penultimate...
