This question already has an answer here:
I had to transform some of my primary variables of interest (log transform). Others were left untransformed as they were normally distributed in the sample (Pfat, etc.). To allow for comparisons of hazards, I was advised to standardize all the variables. I know the hazard ratio is simply exp(Beta Coeff.) but how do I interpret this appropriately if the variables have been both log-transformed and standardized?
I'm not willing to share my data but can provide answers if needed. All the predictors and covariates are explaining disease free survival.
