Calculate a 5-year moving average to forecast the number of mergers for 2012.
Use the moving average technique to determine the forecast for 2005 to 2011. Calculate measurement error using MSE and MAD.
Calculate a 5-year weighted moving average to forecast the number of mergers for 2012. Use weights of 0.10, 0.15, 0.20, 0.25, and 0.30,with the most recent year weighted being the largest.
Use regression analysis to forecast the number of mergers in 2012.
