IC_RR_coxph function

RR and their confidence intervals for Cox models

Computess risk ratios and their confidence intervals for Cox models

IC_RR_coxph(model, alpha = 0.05, sided = 2)

Arguments

• model: a coxph object
• alpha: type I error, 0.05 by default
• sided: 1 or 2 for one or two-sided

Returns

A matrix with the estimaed coefficients of the Cox model, their s.e., z-values, p-values, RR and CI of the RR

Examples

cgd$time=cgd$tstop-cgd$tstart
IC_RR_coxph(coxph(Surv(time,status)~sex+age,data=cgd),alpha=0.05,sided=1)
