- Consider the following time series data: Construct a time series plot. What type of pattern exists in the data? Use a multiple regression model with dummy variables as follows to develop an equation to account for seasonal effects in the data: Qtr1 = 1 if quarter 1, 0 otherwise; Qtr2 = 1 if quarter 2. 0 otherwise; Qtr3 = 1 if quarter 3, 0 otherwise. Compute the quarterly forecasts for next year based on the model you developed in part (b). Use a multiple regression model to develop an equation to account for trend and seasonal effects in the data. Use the dummy variables you developed in part (b) to capture seasonal effects and create a variable t such that t = 1 for quarter 1 in year 1, t = 2 for quarter 2 in year 1, … t = 12 for quarter 4 in year 3. Compute the quarterly forecasts for next year based on the model you developed in part (d). Is the model you developed in part (b) or the model you developed in part (d) more effective?

- CG's full data analysis, 1971-2003, revealed that Market Q was insignificant. That is, there was no impact on firm investment rates from market prices. Why do you think this is the case? Select one: O a. Fundamental Q captures all information relevant to make investment choices. O b. No mis-pricing in any other periods except the 1990s. O c. Fixed Effects in the regression controls for and averages out any time variation in the market prices.arrow_forwardThe historical rate of return on stock A was regressed on the rate of return of stock M (the explanatory variable). The slope of the regression line was 0.8, the standard deviation of the residuals was 0.3 and the standard deviation of the rate of return of M was 0.2. What was the standard deviation of the rate of return on A?

- Beta calculations are subject to which of the following limitations? a. The market's rate of return varies from year to year. b. Beta is known to be erratic and unpredictable. c. Collecting rate of return data on individual assets is difficult. d. Beta is determined from historical data, and the stock's characteristics might have changed since hte measurement was performed.arrow_forwardWhich of the following statements is INCORRECT about the Random Walk Hypothesis? A) It assumes successive returns are statistically independent. B) It assumes there is no correlation between the returns in one period and the next. C) It assumes the distribution of returns in all periods is identical.
