1. Analyze the significance of the variables in Dorothy’s regression model. Develop a regression model (be sure to include additive dummy variables for the seasonal component, if necessary), and use it to forecast the number of new clients for the first three months of 1993. Compare your forecasts with the actual observations. 2. Develop an autoregressive model, and generate forecasts for the first three months of 1993.Which model (multiple regression or autoregression) do you feel is the better candidate for generating forecasts for the rest of 1993? Write Dorothy a memo that provides her with the information she has requested concerning the problem of serial correlation. Include an analysis of the results of your efforts to develop an appropriate model to forecast the number of new clients for the remainder of 1993.
