Dear experts:

I am a newbie to R. Recently, I try to make prediction models with R and the
Design library.
I have read Prof. Harrell's excellent book. But I did not quite understand.
I have two problems about the validation and calibration of prediction
models:
1. Can someone explain the results outputted by the validate() function? How
to get 95% of c-value of validate?
2. How to add 95% ci in the calibration plot?
