Hi Dr. Kabacoff,

Thankyou for an excellent book. I've had it since early in MEAP and it has been extremely useful.

In section 13.2.2, there is a 'trick' where all of the variables are set to their means, except the variable of interest. I am wondering if you could suggest an analogous method I could use if I have predictors that are factors (since I can't use 'mean' on them).
