    we don't have a widely used numerical (non-graphical) measure of calibration. We should replace HL with Harrel's E or E-90, or with the new ICI--which seems almost identical to me. these are pretty easy to interpret, even for a simple country doc.

    Good to raise aware of calibration but Hosmer-Lemeshow test doesn't assess calibration (and has many problems, e.g., summarised in Box G of ), plus there a number of problems with the NRI (e.g., , )
