Enjoy history data has the advantage of while doing so delivering information regarding censored products and you may big date-varying details. Some great benefits of the brand new Cox proportional danger model are one to it comes to almost any theoretic shipments are unnecessary, together with factor estimates try 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 .
