Dear R-Helpers, I am a novice in survival analysis. I have the following code: for (i in 3:12) print(coxph(Surv(time, status)~a[,i], data=a))
I used it to fit the Cox Proportional Hazard models separately for every available parameter (columns 3:12) in my data set - with intention to compare the Hazard Ratios.
However, some of my variables are in range 0.1 to 1.6, others in range 5000 to 9000. How do I compare HRs between such variables?
I have rescaled all the variables to be in 0 to 1 range - is this the proper way to go? Is there a way to somehow calculate the same HRs (as for rescaled parameters) from the HRs for original parameters?
Many thanks in advance. -- Michal J. Figurski, PhD HUP, Pathology & Laboratory Medicine Biomarker Research Laboratory 3400 Spruce St. 7 Maloney Philadelphia, PA 19104 tel.
