stb for proc phreg

Hi,

 

In proc logistic it is possible to get an estimate of the relative covariate strength using the stb option. Does anyone know if there is a similar metric for proc phreg?


Thanks,

Re: stb for proc phreg

Unfortunately there is not an option to get the standardized coefficients in PHREG.  I am not sure these are well defined for a Cox model because the scale of the dependent variable, i.e. time, does not really matter only their rank ordering.  Standardized coefficients usually involve an adjustment by some measure of variation for the dependent variable.  I think you would have to search to find a definition that is compelling to you and then calculate them yourself.
