Multiple Testing Problems in the Context of Modern Portfolio Theory

Finanzmanagement

A multiple testing problem occurs when two or more related null hypotheses are tested simultaneously. The classical significance level, which refers to the type I error of an individual test problem, is not suitable for testing a family of hypotheses. This is due to the fact that more than one true null hypothesis may erroneously be rejected. Several approaches to error control taking account of the multiplicity problem have been proposed. The focus of the present work is…

The Problem of Missing Residential Mobility Information in the German Microcensus

An Evaluation of Two Statistical Approaches with the Socio-Economic Panel

QM – Quantitative Methoden in Forschung und Praxis

The German Microcensus (MC) is a large scale rotating panel survey over three years. Because of its high case numbers and its mandatory participation the MC is a valuable survey for longitudinal analyses within a 3 years frame. A serious obstacle is the missing information about residential movers which is due to the area sampling approach used for the MC. This raises the questions whether longitudinal analyses, like transitions between labour market states, are biased…

GENGED: Visual Definition of Visual Languages

based on Algebraic Graph Transformation

Forschungsergebnisse zur Informatik

Master Ittei said, „In calligraphy it is progress when the paper, brush and ink are in harmony“ [Yam79]. Today in software modeling and specification we are far away from this principle. Visual specifications might be a step in the right direction. We built the GENGED environment to make software modeling and specification easy and reliable. The visual definition of visual languages and the generation of an appropriate editor contains a great potential to bring more…
