Problem 956503: Do not include anything other than numbers in your responses. For example, do not include comma or dollar sign in your numbers. As a rule of thumb, keep 2 decimal places for larger numbers and 3 decimal places for smaller numbers less than 1. Use the following data to calculate the MAD and MSE of the forecasts. Period Demand Forecasts 1 256 2 270 256 3 248 252 4. 265 243 5 244 253 Period Absolute Error 1 2 3 4 5 Calculate the mean absolute deviation (MAD) of the forecasts? Calculate the mean squared errors (MSE) of the forecasts? Problem 515805: Do not include anything other than numbers in your responses. For example, do not include comma or dollar sign in your numbers. As a rule of thumb, keep 2 decimal places for larger numbers and 3 decimal places for smaller numbers less than 1. Consider the following data. We want to monitor the forecasts. Period Demand Forecasts 1 276 2 247 276 3 297 247 4 284 297 5 310 284 Calculate the UCL and LCL for the appropriate control chart to control magnitude of errors? Calculate the cumulative error, MAD, and tracking signals of periods 2 through 5 and determine if the forecasts are biased. Keep two decimal places in your calculations MADS Tracking Signals PeriodErrors Cumulative Errors 1 2 3 4 5 Are forecast errors biased? (Yes/No)
