HeathCo is a manufacturing company that produces a line of skiwear that is sold under various brand names. The Product Manager of HeathCo has contracted with you to develop a model to forecast company sales. You will be supplied with quarterly sales data from 2007 through 2016. They want a model that will allow them to forecast sales one year (four quarters) out. You will use the HeathCo Sales Data worksheet in the HeathCo_Sales.xlsx workbook for this case study. Start your work by running a moving average model, a Holt's exponential smoothing model, and a Winter's exponential smoothing model
