Experience record research provides the benefit of on the other hand delivering details about censored trials and you may date-different parameters. The great benefits of the newest Cox proportional perils model is actually one to it comes to virtually any theoretical shipments is so many, together with factor prices is steady.
The model can be expressed as h(t) = h 0(t)exp(? 1 x 1 + ? 2 x 2 + … + ? k x k) or equally as ln[h(t)] = ln[h 0(t)] + ? 1 x 1 + ? 2 x 2 + … + ? k x k, in which h(t) is the hazard rate for failure over the time t and h 0(t) is the baseline hazard rate 17 .
