Hello community;   I request for assistance. I have failed to come across any published SAS code for calculating  Hosmer Lemeshow statistics and calibration plot in the cox model.    I request for any SAS code that I can modify to suit my data.  I have a variable "PRED" for the survival probabilities from PRC phreg and Status as the censoring variable with "Days" as the variable for  length of follow.     Thank you in advance ...
