Contributions to Credit Portfolio Modeling and Optimization

Survey data are used in many disciplines from Social Sciences to Economics. But might interviewers' behaviour affect the quality of such data? This book presents the results of new research on interviewers' motivation and behaviour. A number of contributions address deviant behaviour and methods for assessing the impact of such behaviour on data.

Identifying factors which stimulate regional growth and international competitiveness and using them for forecasting are the aims of this book. The author proposes the use of heuristic optimization techniques, Monte Carlo simulation experiments and Lasso-type estimators to avoid bias or misleading findings.
