For this reason and by learning different techniques and statistical methodologies, we try to analyze and understand his functioning. Afterwards, I want to explain theoretically the statistical methodologies used to analyze time series that appear in the electrical sector. I make predictions about electrical production to see which method works better and study structural changes after the introduction of the new electric consumption bill. Finally, I carry out a study about the relationship between the industrial production index and the production of electricity and, also, between the consumer price index and the production of electricityapplication/pdfspaElectricity sectorStatistical methodologiesTime seriesPredictionsElectric consumption billinfo:eu-repo/semantics/bachelorThesis2016-09-08info:eu-repo/semantics/openAccess
