Displacement Based Error Metric for Morphodynamic Models

Error Metrics for Business Process Models

Little research has been conducted so far on causes for errors in business process models. In this paper we investigate on how mainly domain independent factors such as the size or complexity of models influence errors observed in a wide range of existing business process models. In particular, we provide a set of six metrics presumably related to the comprehensibility of both the process model...

Morphodynamic models of communication

Morphodynamics means 'the dynamics of form', and the purpose of morphody-namic theories is to describe and explain the birth, evolution, and death of form. The term 'form' is used differently in different sciences, but the notions of discontinuity and organisation seems to recur in most uses. A central question is: how can continuous changes of an amorphous substance, such as increasing the vel...

TESTING FOR AUTOCORRELATION IN UNEQUALLY REPLICATED FUNCTIONAL MEASUREMENT ERROR MODELS

In the ordinary linear models, regressing the residuals against lagged values has been suggested as an approach to test the hypothesis of zero autocorrelation among residuals. In this paper we extend these results to the both equally and unequally replicated functionally measurement error models. We consider the equally and unequally replicated cases separately, because in the first case the re...

Scale-selective Validation of Morphodynamic Models

Although it is generally acknowledged that the practical predictability at smaller scales may be limited, output of high-resolution morphodynamic area models is mostly presented at the resolution of the computational grid. The sopresented fields typically are realistic looking, but not necessarily of similar quality at all spatial scales. Unfortunately, commonly used single-number validation me...
