Chapter 4A, Problem 1E

a)

To determine

To find: The possibility of the cause of autocorrelation.

a)

Expert Solution
Check Mark

Explanation of Solution

The causes of autocorrelation are:

1. Bias in the data

2. The data is not reliable there must be some change in the data.

b)

To determine

To find: The effect of autocorrelation.

b)

Expert Solution
Check Mark

Explanation of Solution

The results are:

1. two or more independent variables are correlated, i.e., multicollinearity.

2. the function might be sometimes non-linear.

c)

To determine

To find: the affect of autocorrelation on the accuracy of forecasts

c)

Expert Solution
Check Mark

Explanation of Solution

  1. autocorrelation might underestimate the true variance.
  2. The null hypothesis might be rejected although it is true.

d)

To determine

To find: remedial for autocorrelation removal

d)

Expert Solution
Check Mark

Explanation of Solution

The remedy is to increase the number of observations, find the missing values and estimators although linear is not the efficient estimator.

XYZ company is interested in quantifying the impact of consumer promotions on the sales of its packaged food product. XYZ has historical data on the following variables for 38 weeks: • Sales: Weekly sales volume in thousands of units.• Prom: Weekly spending on consumer promotions in thousands of Dollars" "A regression analysis was applied to XYZ historical dataset. The dependent variable is weekly Sales and the independent variables are weekly Prom and weekly Lagged Prom (i.e., last week Prom). This is a summary of the regression output:Sales = 0.80 + 1.20*Prom - 0.40*Lag(Prom) • R-squared=0.85• F-Statistic=23.83• p-value=0.001 (for the overall regression)•All regression coefficients are statistically significant at the 5% level." A. What will be the predicted sales volume ? B. What is the gross margin of this net volume impact due to $1000 spending per week on consumer promotions, if brand makes $2.20 gross margin per unit . C. What is the ROI of this promotion? D. What is predicted…
Mita, the manufacturer of copiers, has been spending increasing amounts of money on radio and television advertising in recent years. An analyst employed by Mita wanted to estimate a simple linear regression of the company's annual copier sales versus advertising dollars. Th regression results included SSE = 12593 and SSR = 87663. What is the coefficient of determination for this regression? 0.874 0.935 0.144 0.126
We are interested in understanding consumption of pork in the U.S. so we run a regression of annual per capita consumption of pork on a series of independent variables using data from 1990 to 2018 and obtain the following regression results (standard errors in parenthesis) CPt = -330.3 + 49.1 In Inct − 0.34 PPt + 0.33PBt (7.40) (0.13) (0.12) R²=0.71 DW=0.94 Where CPt is the annual per capita pounds of pork consumed in the U.S. in year t InInc, is the log of per capita disposable income in the U.S. in year t PP, is the average annualized real wholesale price of pork in the U.S. in year t (in cents per pound) PB, is the average annualized real wholesale price of beef in the U.S. in year t (in cents per pound) a. Interpret the partial slope coefficients. Does the sign on the coefficients agree or disagree with your a priori assumptions? Explain b. Using a two-sided test at the 5% significant level, determine if the partial slopes are statistically significant. c. Test the presence of…
