Use of the Correlation Coefficient with Normal Probability Plots
"Use of the Correlation Coefficient with Normal Probability Plots," The American Statistician, Vol. 39 (1985), 75-79 (with S.W. Looney). The use of the correlation coeffeciant is suggested as a technique for summarizing and objectively evaluating the information contained in probability plots. Goodness-of-fit tests are constructed using this technique for several commonly used plotting positions for the normal distribution. Empirical sampling methods are used to construct the null distribution for these tests, which are then compared on the basis of power against certain nonnormal alternatives. Commonly used regression tests of fit are also included in the comparisons. The results indicate that use of the plotting position p sub i = (i - .375)/(n + .25) yields a competitive regression test of fit for normality.
Value-Based Management of Inter-Organizational Business Processes
“Value-Based Management of Inter-Organizational Business Processes,” In Wirtschaftsinformatik ’97, Hermann Krallmann (Editor). Heidelberg: Physica-Verlag, 1997 (with P. Hirschmann and A.-W. Scheer) (Award winning paper, sponsored by the German National Research Foundation’s research program in Distributed Information Systems in Business). Business process management must not be limited to a single enterprise. Just as intra-organizational business processes also inter-organizational ones have to be object of process management. Especially with a view to new forms of cooperation among enterprises the importance of inter-organizational business processes increases. The sub-functions of an overall business process management are the identification, modeling, design, optimization, and implementation of business processes as well as follow-on monitoring and periodical control of all redesigned processes. The execution of these sub-functions requires suitable methods which show the economical consequencces of decision alternatives within the management of inter-organizational business processes. This paper describes a value-based approach for inter-organizational business process management. The approach is based on the analysis of process costs and process revenues. By presenting this approach, U.S.-American and German peculiarities concerning business process management, especially process-oriented accounting methods for process cost evaluation, are considered. The value-based approach is implemented into the prototype of a multi-agent-system named PRINCESS. The system concept as well as its verification and validation in a case-study are also shown.
