[R] Survival Analysis - Cox Regression - Confidence Limits for HR based on Likelihood function
Hallo! Does anybody know how to make R calculate confidence limits for the Hazard Ratio based on the likelihood function when doing Cox Regression? As the p Values and the confidence intervals of Wald statistics differ from the p Value of the likelihood function sometimes "likelihood"-p is <.05 while the 95%-CI is still including 1.
