Design Evaluation Specify Order of Terms to
Ignore
Focus attention on what is most important.

Design Evaluation Evaluate by Design or Response
Useful when a response has missing data.

• New names and limits.
• Internally studentized residual studentized
  residual v6.
• Externally studentized residual outlier t v6.
• The externally studentized residual has exact
  limits.

t(a/n, n-p'-1) p' is the number of model terms
including the interceptn is the total number of
runs
11
Diagnostics DFFITS

• DFFITS measures the influence the ith
  observation has on the predicted value.(See
  Myers, Raymond Classical andModern Regression
  with Applications,1986, Duxbury Press, page
  284.) It isthe studentized difference between
  thepredicted value with observation i andthe
  predicted value without observation i. DFFITS
  is the externally studentized residual magnified
  by high leverage points and shrunk by low
  leverage points. It is a sensitive test for
  influence and points outside the limits are not
  necessarily bad just influential. These runs
  associated with points outside the limits should
  be investigated to for potential problems.
• DFFITS is very sensitive and it is not surprising
  to have a point or two falling outside the
  limits, especially for small designs.

12
Diagnostics DFBETAS
DFBETAS measures the influence the ith
observation has on each regression coefficient.
(See Myers, Raymond Classical and Modern
Regression with Applications, 1986, Duxbury
Press, page 284.) The DFBETASj,i is the number
of standard errors that the jth coefficient
changes if the ith observation is removed.
