Abstract


In order to determine the significant substitute products in each one of the consumption sectors in the Principality of Asturias, the correspondent bivariant and partial statistical correlations of NG against other energies in demand are calculated. The functions among the value-pair sequences of the analyzed variables are linear. The measurement of the dependence level is carried out by Pearson's linear correlation coefficient. To evaluate this coefficient and to confirm whether there exists or not a significant correlation between the variables (p-value<5%) a hypothesis test based on the t-Student distribution is done. The results obtained show a clear substitution of coal by NG.
