Discussion and Results

In this section we present a number of possibly disjoint but important comments with the purpose of achieving two objectives. One is to discuss the results of how the various models performed in comparison with each other. The second is to discuss the details of what the various performance measures convey, how they complement each other and what their drawbacks are. For convenience we shall refer to the models by the numbers associated with them in section  and to the performance measures by the numbers associated with them in section . The numbers are also consistent with the order in which we presented the models and the measures.
