In this paper we apply statistical inference techniques to build neural network models which are able to explain the prices of call options written on the German stock index DAX. By testing for the explanatory power of several input variables serving as network inputs, some insight into the...

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 Anwendung neuronaler Netzwerke ist ein extrem kontrovers diskutiertes Thema. In dem einen Extrem erhoffen die Verfechter neuronaler Netzwerke, daß diese als Produkt der 'künstlichen Intelligenz' in der Lage sind, Aufgaben zu lösen, die bislang als unlösbar oder nur schwer lösbar galten....
