[R] validate.lrm - confidence interval for boostrap-corrected AUC ?
Hi Does anyone know whether the rms package provides a confidence interval for the bootstrap-corrected Dxy or c-index? I have fitted a logistic model, and would like to obtain the 95% confidence interval of the bootstrap-corrected area under the ROC curve estimate. Thanks. [[alternative HTML version deleted]]

It does not offer that feature. That is an area of active research. If anyone knows of a paper that has solved this problem please let me know.
