Fuzzy number approximations provide a robust framework for representing and managing uncertainty in quantitative analyses. By generating simplified yet accurate representations of fuzzy ...

We consider complexity penalization methods for model selection. These methods aim to choose a model to optimally trade off estimation and approximation errors by minimizing the sum of an empirical ...

This research investigates how the relationships among pieces of numerical information in a price promotional offer (i.e., regular price, sale price, absolute discount, and relative discount) affect ...
