Using GMDH for modeling economical indices of mine opening
Ljudmila Sarycheva · Systems Analysis Modelling Simulation · 2003
Dependency of explicit costs index of mining opening on its parameters is modeled. In addition, the problem of structural identification is solved. Models enumeration is realized with the help of group methods of data handling (GMDH). Least-squares and least-modules methods are used for evaluating model parameters. The quality of resulting models is evaluated by the following criteria: (a) remaining sum of squares criteria; (b) sliding control criteria; (c) regularity criteria.
