Question 2 As noise increases in a time series, which of the following will be more difficult to find? Seasonality Trend O R-squared O Cycles Question 3 If not properly modeled, what violation of the regression assumptions can be caused by auto-correlation of the dependent variable? O Linearity O Normality O Independence of errors O Equal variance Question 4 Which of the following statements about forecasting are correct? After you select a particular forecasting model, you do not need to continually monitor your forecasts. Extrapolation (smoothing methods) & econometric models are both types of quantitative forecasting methods. When a time series increases at a rate such that the percentage difference from value to value is constant, an exponential trend is present.
