Calculate (a) MAD and (b) MSE for the following forecast versus actual sales figures: a) MAD= (round your response to one decimal place). b) MSE = (round your response to one decimal place). The number of intemal disk drives (in milions) made at a plant in Taiwan during the past 5 years follows: a) Using simpie linear regression, the forecast for the mumber of disk drives to be made next year = disk drives (round your response to one decimal place b) The mean squared error (MSE) when using simple linear regression = drives 2 (round your response to one docimal place). c) The mean abisoluae percentage error (MAPE) when using simple linear regression = %6 (round your response to one decimat place)
