In economics, many quantities are related to each other. Sucheconomic relations are often much more complex than relations inscience and engineering, where some quantities are independenceand the relation between others can be well approximated by linearfunctions. As a result of this complexity, when we applytraditional statistical techniques -- developed for science andengineering -- to process economic data, the inadequate treatmentof dependence leads to misleading models and erroneous predictions.Some economists even blamed such inadequate treatment of dependencefor the 2008 financial crisis.
