Dear list Is there anywhere I could find further information on how to interpret the output for a logistic regression for validate() from Design package?. I tried ?validate and google but I cannot find information on what the rows and the columns represent. Thanks David

My copy's index has 15 entries under validate. Section 10.9 is a 5 page discussion that looks very on-point. An broad Google search: "harrell, FE" validate regression , not surprisingly produced numerous other citations. Frank's been at this validation effort a while. -- David Winsemius
