ECONOMETRICS An econometrician wanted to investigate the effects of family size () and income () on household consumption expenditure (). Using a sample size of 89 households he obtained the following results in deviation form. 50.5   -66.2 36.8 -66.2       967.1   39.1 0.0218   0.0015 0.0015   0.0011 , , , […]

Describe how to interpret the parameters of the recorded model. Is there a reason to prefer one coding over the other?

Programming – Altering Dummy Variable Values Consider the two variable regression problem with a dummy variable in the design matrix: g = /30 + thi+ 71+ e, where 1 is a dummy-variable that is coded 1 if the observation satisfies a certain condition, and is 0 ti otherwise. Consider replacing the 0 and 1 values […]

Comparing the two equations, which model has estimated signs corresponding to your prior expectations? Can one argue that model 2 is preferred on the basis of fit?

ASSIGNMENT Consider the following two least-squares estimates of the relationship between interest rates and the federal budget deficit in the United States: Model 1: N = 56, R2 = 0.00 where: = Interest rate on AAA corporate bonds = Federal budget deficit as percentage of GNP Model 2:   .369 N = 38, R2 = […]

Discuss the appropriateness of using simple linear regression and make any recommendations regarding the prediction of overall score using just the price of the camera.

CASE ASSIGNMENT Read the Case Problem 3 (Selecting a Point and Shoot Digital Camera) presented at the end of Chapter 14 in the textbook. Answer the following questions: Develop numerical summaries of the data. Using overall score as the dependent variable, develop three scatter diagrams, one using price as the independent variable, one using the […]

Explain why your regression equation was implemented the way you defined it, and how you believe your explanatory variables and controls are adequate.

Econometrics Project Introduction The econometrics project will be an opportunity to apply the concepts learned in class to write an empirical paper on a topic of choice. Students will need to select a topic, formulate a research question, and apply the analytical and quantitative skills acquired in this course to a data set to answer […]

Calculate the coefficient of determination. Determine the regression equation. Is there a positive association between the size of the house and its selling price?

Correlation coefficient 1-A sample of 12 houses that were sold last week in San Juan is selected. Can we conclude that, as the size of the house (reported in thousands of square feet in the table below) increases, so does the sale price. The following table in thousands of square feet), the selling price (reported […]
