Dear Stata-listers

The calibration of  a prognostic score may be examined by Hosmer-Lemeshow goodness-of-fit statistics. Another way to examine (and present it) is by so called calibration curves, i.e. a plot of observed f.ex. mortality (with 95% CI) against predicted mortality within deciles of risk with a diagonal representing perfect predictive ability.

Does anyone have a suggestion how to create such calibration curves after a logistic regression model in Stata 8 ?

Thank you in advance.
