Extrapolating this analysis to the remaining periods, it is possible verify that the electricity prices register lower values for the summer months, where the EC-P is smaller. It should be noted that models for Portuguese and Spanish markets interrelate the electricity price with explanatory variables for each country. Kalsie A. Then, it can be concluded that there is an infringement of the independence of the error term and that this model suffers from autocorrelation of the errors. The main purpose of the modelling and forecasting processes is to clearly discern the future values of the dependent variable, and the most important criterion of all is how accurately a model does this. Sze N. Profitability refers to the company's ability to make profits under normal operating conditions. Liu W. Nunkoo R. Is there a relationship between the physical attractiveness of a professor and their student evaluation scores? Farag R. Although there are various measures of forecasting accuracy that can be used for forecast evaluation, in this work it is used the mean absolute percentage error MAPE expressed in generic percentage terms, computed by Equation 3 [ 20 ]:.

Our selection of financial indicators is not comprehensive enough, and the analysis method is mainly based on multiple statistical regression. Candra A. It is also noteworthy the growing use of hybrid models, combining those methodologies, as described mulhiple [ 18 ]. The major contribution of this research is the proposal of the use of the system dynamics approach to develop a multiplf of transition from a multiple regression predictive model to a simpler nonlinear regression explanatory model, which increases the level of prediction of the model.
