Finding parameter estimates for a proportional hazards model is an iterative procedure. When the fitting is complete, the report in The Proportional Hazards Fit Report appears.
Shows the parameter estimates for the covariates, their standard errors, and 95% upper and lower confidence limits. A confidence interval for a continuous column that does not include zero indicates that the effect is significant. A confidence interval for a level in a categorical column that does not include zero indicates that the difference between the level and the average of all levels is significant.
