Lurking variables are those that were not included in regression analysis, but are actually the true independent variable. For example, studies show that where there is an increase in ice cream sales, there is also an increase in the number of drownings. Now, ice cream does not affect drowning. The lurking variable in this case is the temperature. As the temperature rises, people buy ice cream and they go swimming. More people swimming will increase the number of drownings. Statisticians need to think about potential lurking variables.

When creating a regression model of what impacts sales at the movies, what independent variables might we include? What might be some lurking variables that would be harder to include directly?

Explain the difference between correlation analysis and regression analysis. Give an example of a lurking variable. If a statistician computed a value of r = -2.83 what would you tell that statistician? Under what circumstances can we calculate r? Can the regression equation be assumed to hold 100 years from now? Are there other correlation coefficients other than the Pearson Product Moment Correlation Coefficient

Can you say that the coffee is the reason for the poor health or is there a lurking variable as the actually cause?

Over the years it has been said that coffee is bad for you. When looking at the studies that have shown that coffee is linked to poor health, you will see that people who tend to drink coffee don't sleep much, tend to smoke, don't eat healthy, and tend to not exercise. Can you say that the coffee is the reason for the poor health or is there a lurking variable as the actually cause?

Explain why two perfectly multicollinear regressors cannot be included in a linear multiple regression. If those same two regressors were not perfectly collinear but highly collinear what difference, or differences, would that make? Give an example of a pair of perfectly multicollinear regressors.

Discuss some of the possible" lurking variables" that may exist below. Researchers observe that there is a correlation between the number of glasses of red wine a person drinks per week, and the number of illnesses the person has. They conclude that drinking red wine causes a person to be healthier.

In a single variable regression analysis the respective values for the variables are as follows: Independent variable: 2.00, 7.00, 11.00, 16.00, 13.00, 14.00, 1.00, 12.00, 19.00, 9.00. Dependent variable: 58.78, 44.64, 33.27, 16.04, 26.72, 24.89, 63.11, 28.41, 7.66, 39.20. What is the predicted value of the dependent variable when the independent variable is equal to 15.00?

Discuss what are some of the possible "lurking variables" that may exist from the below scenario. A correlation was found between high blood pressure and cancer rates. (People with high blood pressure were more likely to develop cancer than people with low blood pressure.) It was concluded that high blood pressure causes cancer.

True or False: Regression analysis is used for prediction, while correlation analysis is used to measure the strength of the association between two numerical variables. A. True B. False In performing a regression analysis involving two numerical variables, we are assuming A. the variances of X and Y are equal. B. the variation around the line of regression is the same for each X value. C. that X and Y are independent. D. All of these. Which of the following...

If I ran a multivariate regression analysis for the effect of independent variables X and Y on dependent variable A, that produced an adjusted R^2 of .0553, then added the independent variable Z to the analysis and got an adjusted R^2 of .0550, would that decrease in the adjusted R^2 translate to the independent variable Z not being a strong predictor of the dependent variable A? If it were a strong predictor of A would the adjusted R^2 increase?
