Query: A new approach in model selection for ordinal target variables   This paper introduces a novel approach to assess model performance for
predictive models characterized by an ordinal target variable in order to
satisfy the lack of suitable tools in this framework. Our methodological
proposal is a new index for model assessment which satisfies mathematical
properties and can be easily computed. In order to show how our performance
indicator works, empirical evidence achieved on a toy examples and simulated
data are provided. On the basis of results at hand, we underline that our
approach discriminates better for model selection with respect to performance
indexes proposed in the literature.
