WebbWhen interaction terms are included in a Cox Proportional Hazards model, it is very tricky to compute the hazard ratio (HR) and, especially, the confidence intervals. To compute confidence intervals using proc PHREG, we can get the variance of the interaction terms by using the estimated covariance matrix of the parameter estimator.
