Abstract

After the model parameters have been determined, a sensitivity analysis should be carried out. A test for the significance of the model parameters normally allows a model reduction. Furthermore, from the viewpoint of interpretation it is of interest on which factors the utility and distance functions of the considered behavioural changes depend. A corresponding decomposition with respect to explanatory variables is possible by means of a regression analysis in connection with a factor analysis or, alternatively, a ranking regression analysis. This is especially important for the prognosis of the future behaviour of the investigated system. Examples for the decomposition of utility functions into interpretable contributions will be discussed for purchase pattern and voting behaviour.
