Modified H–L χ2 statistic for survival data

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
