Produces a summary of a fitted coxph model
## S3 method for class 'coxph' summary(object, conf.int=0.95, scale=1,...)
object |
the result of a coxph fit |
conf.int |
level for computation of the confidence intervals. If set to FALSE no confidence intervals are printed |
scale |
vector of scale factors for the coefficients, defaults to 1. The confidence limits are for the risk change associated with one scale unit. |
