Continuity Correction and Standard Error Calculation for Testing in Proportional Hazards Models

Stats
Standard asymptotic inference for proportional hazards models is conventionally performed by calculating a standard error for the estimate and comparing the estimate divided by the standard error to a standard normal distribution.
