STAT 704 Fall 2016 ------------------ Homework 7 ---------- Do the following problems from the textbook: 10.2, 10.3, 10.8, 10.11(a,b,d), 10.12(a,b,d), 10.26. 8.12, 8.13, 8.14, 8.16, 8.21, 8.22, 8.27, 8.28, 8.34, 8.35(a,b)** 16.1, 16.2, 16.4(b), 16.6, 16.8(b,c,d,e,f), 16.10(b,d,e,f), 16.15, 16.19(a,b,c) NOTE: For 10.11(a) & 10.12(a), you may find the internally studentized residuals and compare their absolute values to 2.5 instead of doing the Bonferroni outlier test. For 10.11(d) and 10.12(d), don't worry about the DFBETAS. NOTE: On page 359 and page 433, the book's notation sigma^2{.} is equivalent to: var{.} NOTE: For 8.16(d), if this plot shows random scatter, then the interaction term is probably not necessary. **NOTE: For 8.35(b), note the book has an error in equation (6.25). It should be: b = (X'X)^{-1} X'Y The relevant data sets can be found on the course web page.
