Example of Two Multiple Regression Fitted Equations That Can Be Graphed
 |
| LOS = B0 + B1*age + B2*nnurses |
 |
| LOS = B0 + B1*age + B2*nnurses + B3*age*nnurses +B4*age^2 + B5*nnurses^2 |

Hello Biostat 2 Students. Review problems from Chapter 12 in B1 Book.
For Week 1 of the semester I would like for you to review Chapter 12 and see if you can work problems:
12.23(a,c,d,e)
12.25 (b,c,d),
and 12.59 (b,c,d) (the printout provides CI and estimate for problem d).
I recommend that you look at the problems first so you can have an idea of the concepts you need to be looking for in the chapter. The book goes through some arithmetic on calculation of the slope, intercept, and sums of squares for the AOV. Don't worry so much about these calculation details. We will rely on software to calculate these for us. I would like for you to review the printouts and the interpretation of the values therein. We will go over these items on the second week of class.
