The CoxHazardRatio function takes as input the coefficient table output by the function CoxPH (ML Engine) and outputs the hazard ratios between predictive features and either their corresponding reference features or their unit differences.

The CoxPH and CoxHazardRatio functions do not support interaction terms (for example, using AGE*AGE as an item in the Cox proportional hazard model). The CoxHazardRatio function supports only relative hazard ratio calculation. It does not calculate or output confidence intervals.
