In this paper, based on well-established behavioral theories, we propose a new model for dynamic formation of customer’ quality expectations. The model is described by a one-dimensional non-linear discrete dynamical system which depends on several parameters with links to behavioral theories....

The classical approach to testing for structural change employs retrospective tests using a historical data set of a given length. Here we consider a wide array of fluctuation-type tests in a monitoring situation – given a history period for which a regression relationship is known to be...

The paper presents an approach to the analysis of data that contains (multiple) structural changes in a linear regression setup. We implement various strategies which have been suggested in the literature for testing against structural changes as well as a dynamic programming algorithm for the...
