The worksheet Sterling in the Chp 17 HW problems data workbook on Moodle shows the daily spot exchange rate in U.S. dollars per pound Sterling. a) Use simple regression with rate as the independent or Y variable and Day as the dependent or X variable to fit the data. Determine MAD, MSE and MAPE for the simple regression model. Construct a chart that has the observed data and the fit line by Day. Use the simple regression model to predict spot exchange rate for the next day, i.e., t = 43. b) Use a four time period Moving Average to fit the rate data. Determine MAD, MSE and MAPE for the Moving Average model. Construct a chart that has the observed data and the fit line by t. Use the Moving Average model to predict spot exchange rate for the next day, i.e., t = 43. c) Use exponential smoothing with a smoothing constant of 0.25 to fit the data. Determine MAD, MSE and MAPE for the exponential smoothing model. Use the model to forecast housing starts for the next year, i.e., year 23. d) Short answer. Which of the three above forecasting models (simple regression, moving average and exponential smoothing) would you use to model the data and why would you use that model.

the daily spot exchange rate in U.S. dollars per pound Sterling.
a) Use simple regression with rate as the independent or Y variable and Day as the
dependent or X variable to fit the data. Determine MAD, MSE and MAPE for the
simple regression model. Construct a chart that has the observed data and the fit
line by Day. Use the simple regression model to predict spot exchange rate for
the next day, i.e., t = 43.
b) Use a four time period Moving Average to fit the rate data. Determine MAD,
MSE and MAPE for the Moving Average model. Construct a chart that has the
observed data and the fit line by t. Use the Moving Average model to predict spot
exchange rate for the next day, i.e., t = 43.
c) Use exponential smoothing with a smoothing constant of 0.25 to fit the data.
Determine MAD, MSE and MAPE for the exponential smoothing model. Use the
model to forecast housing starts for the next year, i.e., year 23.
d) Short answer. Which of the three above forecasting models (simple regression,
moving average and exponential smoothing) would you use to model the data and
why would you use that model.
