In this article we examine how model selection in neural networks can be guided by statistical procedures such as hypotheses tests, information criteria and cross validation. The application of these methods in neural network models is discussed, paying attention especially to the identification...

Die Klimaschutzdiskussion wird von der Frage dominiert, welche gesamtwirtschaftlichen Kosten mit der Umgestaltung des Energiesystems zu klimaverträglichen Strukturen verbunden sind. Höhe und Verteilung dieser Kosten entscheiden darüber, ob sich umweltpolitische Strategien zum nachhaltigen...
