The brand new Cox proportional risks model, a commonly used model at this moment enjoy investigation, try employed to analysis Chinese remarriage and its particular impacting procedure. Skills records study gets the benefit of while doing so bringing information regarding censored products and date-differing parameters. The key benefits of the new Cox proportional risks model was you to it comes down to virtually any theoretic distribution is actually too many, in addition to parameter estimates are stable.
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 .
