Dear all,

I'm trying to assess model calibration using modified H–L χ2 statistic according to equation (3.2) or (3.50) written in the following reference:

http://www.sciencedirect.com/science/article/pii/S0169716103230017

Now I 'm writing a sas macro to estimate the modified H–L statistic .

And I want to check my sas code if there any other sas macros available or published.

I would be very grateful if someone would give me information about this.

Thanks in advance,

Yasu

Since most of use aren't going to $30 to read the text of the article you might need to find another reference.

What does the H-L stand for? We may be able to find another source.

Dear ballardw,

Thank you for your reply and I apologize my explanation was not enough.

The H-L statistic stands for the Hosmer-Lemeshow statistic and you can view the reference article at the following link (though it might be the draft version):

Your continued support will be greatly appreciated.

Does http://www.ats.ucla.edu/stat/sas/seminars/sas_logistic/logistic1.htm help at all? This page has an example with PROC LOGISTIC.

Than you for your continued help.

Yes, I know the conventional Hosmer-Lomeshow test for binary data can be conducted with lackfit specification in Proc Logistic.

But I want to conduct the modified one for survival data. D'Agostino and Nam introduced it and a lot of authers have been refering to this article. So I think SAS macro code can be available or published.

Thanks,

Yasu

According to the following article :

http://www.biomedcentral.com/1471-2458/12/79

Dr Haider Mannan from Monash U. has programmed a modified HL-test macro. His coordinates are here:

he might be able to save you a lot of time and effort.

Hi Yasu

Did you get or code the macro for calibration in survival analysis?

Thank you
