Chapter 10, Problem 10.43P

Multiple regression (continuation of 10-42). After further discussion, Julie and Rhett wonder if they should view both the number of procedures and number of patient-hours as cost drivers in a multiple regression estimation in order to best understand Apollo’s medical supplies costs.

  1. 1. Conduct a multiple regression to estimate the regression equation for medical supplies costs using both number of procedures and number of patient-hours as independent variables. You should obtain the following result:

    Required

Regression 3

Medical supplies costs = a + (b1 × No. of procedures) + (b2 × No. of patient-hours)

Chapter 10, Problem 10.43P, Multiple regression (continuation of 10-42). After further discussion, Julie and Rhett wonder if

  1. 2. Evaluate the multiple regression output using the criteria of economic plausibility goodness of fit, significance of independent variables, and specification of estimation assumptions.
  2. 3. What potential issues could arise in multiple regression analysis that are not present in simple regression models? Is there evidence of such difficulties in the multiple regression presented in this problem? Explain.
  3. 4. Which of the regression models from Problems 10-42 and 10-43 would you recommend Julie Chen use? Explain.

Recent research into the cost of various medical procedures has shown the impact of certain complications encountered in surgery on the total cost of a patient’s stay in the hospital. The researchers used regression analysis and found the following results:   Total cost for patient = Constant, plus   a × Length of stay (measured in days), plus b × Presence of one or more complications (= 1 if true, 0 if false), plus c × Use of a laparoscope (= 1 if true, 0 if false)   where a, b, c are coefficients of the regression model. The laparoscope is an instrument somewhat like a miniature telescope with a fiber-optic system that brings light into the abdomen. It is about as big around as a fountain pen and twice as long.   The research, based on 63 patients, showed the following regression results:   R-squared: 56% Constant term: $3,158   Coefficients and t-values for independent variables:     Length of Stay Complications Laparoscope Coefficient $ 887 $ 1,912 $ 928 t-value 7.51 5.30…
Tom uses his computer to calculate the following regression formula:Weekly total costs = $18,791 + ($19.97 * Number of orders per week) Draw the regression line on your graph. Use your graph to evaluate the regression line using the criteria of economic plausibility, goodness of fit, and significance of the independent variable. Is the cost function estimated using the high-low method a close approximation of the cost function estimated using the regression method? Explain briefly.
A chemical engineer working for a large chemical products company was asked to make a recommendation about which of three mutually exclusive revenue alternatives should be selected for improving the marketability of personal care products used for conditioning hair, cleansing skin, removing wrinkles, etc. The alternatives (X, Y, and Z) were ranked in order of increasing initial investment and then compared by incremental rate of return analysis. The rate of return on each increment of investment was less than the company’s MARR of 17% per year. The alternative to select is: (a) DN (b) Alternative X (c) Alternative Y (d) Alternative Z
