This paper proposes a data-driven identification of bank outputs and inputs using the directional technology distance function. While previous applications of this tool used symmetric expansion or ...

Description: Dimensions: 20 For input variable screening purposes, it can be found that some input variables of this function have a very high effect on the output, compared to other input variables.

This function's a-coefficients are chosen so that 5 of the input variables contribute significantly to the output variance, 5 have a much smaller effect, and the remaining 5 have almost no effect on ...
