Hello
Thanks to Frank Harrell for the great Design package. I noted from Pencina's
Article (Statistics in Medicine Vol 27, pp157-172) that the result obtained for
the Net Reclassification Index depends upon categorical cut-offs for risk (eg
in the paper <6%, 6-20% and >20%). I wondered how the improveprob function
arrives at its cut-offs, and whether there was any function to change the
default cut-offs used.
Thanks for any help you can offer.
Yours sincerely
David McAllister
