summary.coxph {survival} | R Documentation

## Summary method for Cox models

### Description

Produces a summary of a fitted coxph model

### Usage

    ## S3 method for class 'coxph'
    summary(object, conf.int=0.95, scale=1,...)

### Arguments

`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.
`...` | for future methods

### Value

An object of class `summary.coxph`.

### See Also

coxph, print.coxph

### Examples

    fit <- coxph(Surv(time, status) ~ age + sex, lung)
    summary(fit)
