Explain why the moving average method was used instead of another forecasting method. What might be another forecasting method that could prove to be just as useful? Your initial post should be 200-250 words.

2007 123
2008 97
2009 186
2010 225
2011 240
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.
