Closed Form Integration of Artificial Neural Networks With Some Applications to Finance

Gottschling, Andreas; Haefke, Christian; White, Halbert - 1999

Many economic and econometric applications require the integration of functions lacking a closed form antiderivative, which is therefore a task that can only be solved by numerical methods. We propose a new family of probability densities that can be used as substitutes and have the property of...
