Cox proportional hazard model calibration plots and Hosmer lemeshow test

Joseph2010 — Tue, 01 May 2018 10:41:38 GMT

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

Hello our esteemed experts,

I have tried to look for SAS codes how to calculate calibration in cox model and obtain plots but I have failed to find any material to follow,

Request to be assisted

Thanks

Try this Google search for calibration plots

phreg calibration plot site:sas.com

There are lots or articles out there.

The Hosmer-Lemeslow statistic is designed for logistic regression, not proportional hazards regression. A Google search showed a fairly recent dissertation (2012) on the extension from logistic to proportional hazards regression. Such a recent (and not further published) extension does not bode well for finding the code online.
