Abstract:
This study aims to apply the Cox proportional hazard regression model to the ties event
using two approach methods, ie the Efron approach and the Exact approach and find out
its application in the case of traffic accidents at Pekanbaru city. The accident data was
taken from the Satlantas Polrestabes Pekanbaru on 2020. There are four variables that are
considered in this study, ie age, gender, helmet use, and driver’s license ownership. After
testing the best Cox model, the two approaches used gave the same results where there
were three significant variables, driver’s license ownership, gender, and age. Then, the
proportional hazard assumption was tested, where all variables met the proportional
hazard assumption
