Please let me adress a question about forecasting.
My database includes annual consumption of residential electricity from 1980 till 2007. I am forecasting consumption of electricity from 2008 till 2020.
I have regressed a simple model:
Energy(t) = a0 + a1Energy(t-1) + a2Pop(t) + u
Population till 2020 is known, so I assume it is a conditional forecasting.
All I need is the confidence interval of my multiple-step ahead forecast and a graph showing observed data, predicted curve, forecast and shaddowed area of the confidence interval.
Sorry if the question is too easy.
