a. Report the measure of accuracy: MAE. Round your answer to four decimals. b. Report the measure of accuracy: RMSE. Round your answer to four decimals. c. Report the measure of accuracy: MAPE expressed as a percent. (Convert to a percent and round to two decimals. For instance, if your answer is 0.0123, it will become 1.23%, but do not type the percent sign, so it's just 1.23) d. Using the trend equation developed, forecast revenue in year 11. Round the answer to four decimal places. e. Does autocorrelation appear to be a problem? Plot the forecast error against the time variable. Compute the DW test statistic. (Round to three decimals.)
