In "Credit Scoring for Risk Managers: The Handbook for Lenders" by
Elizabeth Mays, chapter 4 page 68, it says that the coeffients from
the logistic regression are multiplied by a factor equal to the number
of points for which we want a doubling of the odds to occur, and then
divided by ln(2). Is the multiplication a standard practice? Why it is
multiplied by say 20/ln(2)? How do we determine what factor to
multiply? Is 20 a standard factor?
Hope anyone can help me!
Thanks in advance!

Perhaps I can help future readers by suggesting that you learn to cross-
post properly. You multiposted an identical (and perfectly reasonable)
question to more than one technical groups, and that practice is considered
wasteful of both your time and ours.
Check responses in sci.stat.math.
