Event record study comes with the benefit of concurrently getting information about censored examples and you can go out-differing parameters. The advantages of the new Cox proportional potential risks model are you to definitely it comes to virtually any theoretical distribution try so many, therefore the parameter quotes is actually secure.
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 her 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 .
