Hazard ratio r
WebInterpreting the output from R This is actually quite easy. The coxph() function gives you the hazard ratio for a one unit change in the predictor as well as the 95% confidence interval. Also given is the Wald statistic for each parameter as well as overall likelihood ratio, wald and score tests. WebProvides flexible hazard ratio curves allowing non-linear relationships between continuous predictors and survival. To better understand the effects that each continuous covariate has on the outcome, results are expressed in terms of hazard ratio curves, taking a specific covariate value as reference. Confidence bands for these curves are also derived.
