Information at the interface between supply and demand for indicators: the use of a model with estimated parameter values as a base for indication in multicriteria analyses

An indicator must be defined according to at least three points of view. It must be a parameter of a model according to which the objective of the decision can be represented; it must be an argument of a decision function; and it must be estimable through a function of available data. The whole set of estimates of the parameters of a model is a multidimensional statistic, i.e. a set of functions ...
