Administration Regression Part 2. Statistical Inference. Class Examples Replicate the class examples exactly as demonstrated in the class lecture. Pay equal attention to the accuracy of the analytical techniques you use to solve the problem and your interpretation of the results. Be sure to include textboxes/comments of your interpretation and conclusions for every piece of output generated. Submit your worked data in a single MS Excel Workbook. Create separate (appropriately labeled) worksheets within a single workbook for each example. Regression Part 2 PUAD 630 Class Examples Page | 2 Example 1. Bendrix has collected data for overhead costs, machine hours and the number of production runs corresponding to 36 months of production. Estimate the regression for overhead costs at Bendrix as a function of both machine hours and production runs. A. Interpret the point estimates and comment on the accuracy of the point estimates. B. Comment on if and why each explanatory variable should/should not be included in the regression equation. C. Run the usual multiple regression and check the graph of residuals versus fitted values. Check for lag 1 autocorrelation in two ways: with the DW statistic and by examining the time series graph of the residuals. D. Suppose Bendrix expects the values of Machine Hours and Production Runs for the next three months to be 1430, 1560, 1520, and 35, 45, 40, respectively. Predict Overhead at Bendrix for the next three months, given the anticipated values of Machine Hours and Production Runs. Example 2. Simulation is used to generate a hypothetical data set of heights and left and right foot lengths where height is approximately 31.8 plus 3.2 times foot length (all expressed in inches). Estimate a regression when both Right and Left are entered in the equation for Height and check for multicollinearity in your model. Regression Part 2 PUAD 630 Class Examples Page | 3 Example 3. The data include 750 customers who purchased mail-order products from a HyTex catalog. For each customer, data is available for:  Age of the customer  Gender  Whether they own their home  Whether they are married  Whether they live reasonably close to a shopping area that sells similar merchandise  Combined annual salary of customer and spouse (if any)  Number of children living with customer  Whether they purchased from HyTex during the previous year  Total amount of purchases made from HyTex during the previous year  Number of catalogs sent to the customer this year  Total amount of purchases made from HyTex this year A. Estimate a regression equation for Amount Spent based on all of these variables. B. Choose either the forward, backward, or stepwise procedure and interpret a regression equation for Amount Spent based on the included variables. Example 4. The data set includes the following variables for each of the 208 bank employees:  Education (categorical)  Grade (categorical)  Years1 (numerical. years with this bank)  Years2 (numerical. years of previous work experience)  Age (numerical)  Gender (categorical with two values)  PCJob (categorical yes/no for if employee's current job is primarily computer-related)  Salary (numerical) A. Run a regression analysis with Salary as the dependent variable, and Education, Years1, and Gender as explanatory variables. Also include an interaction variable to see whether the effect of Years1 is different across the two genders. Examine the data for any outliers using boxplots and scatterplots of the residuals versus the fitted values. B. If outliers are identified, rerun the regression without the outlier(s) and interpret the results. Comment on the effect of including/excluding the outlier(s).
