Monthly electricity consumption data for two years is given by
data2={464, 675, 703, 887, 1139, 1077, 1318, 1260, 1120, 963, 996,960, 530, 883, 894, 1045, 1199, 1287, 1565, 1577, 1076, 918, 1008,1061}
and it is plotted in figure below.
Forecast the next years (monthly) electricity consumption by employing an appropriate Holt-Winters method. Let α= 0:2 β= 0:1 y= 0:1: Determine
the initial values for level, trend and seasonality. Do not USE EXCELL seasonal forecasting commands. Show your intermediate results.

You have monthly data on gasoline prices in two cities—Vancouver and Toronto, for the years 2006–2010. In each month of each year, you observe the average price of gasoline in each city. Prices in Vancouver are usually higher than in Toronto, but the cities follow similar price trends, as prices rise in the summer months and respond similarly to demand and cost shocks. However, there are month-to-month fluctuations for various reasons. Starting from January 1, 2008, Vancouver imposed a carbon...
